No mundo material isso seria realmente surpreendente porque as part\u00edculas magn\u00e9ticas s\u00e3o normalmente observadas como dipolos &#8211; os polos Norte e Sul combinados. No entanto, existem diversas teorias que predizem a exist\u00eancia de monopolos. Entre outros, em 1931 o f\u00edsico  Paul Dirac foi levado por seus c\u00e1lculos \u00e0 conclus\u00e3o de que monopolos magn\u00e9ticos poderiam existir nas extremidades de tubos &#8211; chamados de Cordas de Dirac &#8211; que conduzem um campo magn\u00e9tico.

O material sob investiga\u00e7\u00e3o era um \u00fanico cristal de Titanato de Dispr\u00f3sio. Este material se cristaliza em uma geometria not\u00e1vel, a assim chamada estrutura-pirocl\u00f3rica (<i>pyrochlore-lattice<\/i>). Com o aux\u00edlio do espalhamento de n\u00eautrons,  Morris e  Tennant mostram que os momentos magn\u00e9ticos dentro do material se reorganizaram no assim chamado &#8220;Espaguete-de-Spins&#8221; (<i>&#8220;Spin-Spaghetti&#8221;<\/i>).&nbsp; Esse nome vem do ordenamento dos pr\u00f3prios dipolos, de forma tal que surge uma rede de tubos contorcidos (cordas), atrav\u00e9s dos quais passa o fluxo magn\u00e9tico. Estes podem ser tornados vis\u00edveis atrav\u00e9s de sua intera\u00e7\u00e3o com os n\u00eautrons que t\u00eam, eles mesmos, um momento magn\u00e9tico. Dessa forma, os n\u00eautrons se espalham de uma forma que reproduz os momentos das cordas.<\/p>\n<p>Durante as medi\u00e7\u00f5es do espalhamento dos n\u00eautrons, os pesquisadores  aplicaram um campo magn\u00e9tico ao cristal. Com este campo eles podiam influenciar a siemetria e a orienta\u00e7\u00e3o das cordas. Dessa forma foi poss\u00edvel reduzir a densidade das redes de cordas e promover a dissocia\u00e7\u00e3o do monopolo. Como resultado, em temperaturas de 0,6 a  2 Kelvin, as cordas ficam vis\u00edveis e t\u00eam monopolos magn\u00e9ticos em suas extremidades.<\/p>\n<p><!-- Begin image here --><\/p>\n<table align=\"right\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"218\">\n<tbody>\n<tr>\n<td colspan=\"5\"><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"10\" width=\"1\" \/><\/td>\n<\/tr>\n<tr>\n<td><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"8\" \/><\/td>\n<td align=\"left\" bgcolor=\"#f2f2f2\" height=\"4\" valign=\"top\" width=\"4\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/corner_tl.jpg\" alt=\"\" border=\"0\" height=\"4\" width=\"4\" \/><\/td>\n<td bgcolor=\"#f2f2f2\" height=\"4\" width=\"210\"><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"10\" width=\"1\" \/><\/td>\n<td align=\"right\" bgcolor=\"#f2f2f2\" height=\"4\" valign=\"top\" width=\"4\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/corner_tr.jpg\" alt=\"\" border=\"0\" height=\"4\" width=\"4\" \/><\/td>\n<td><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"8\" \/><\/td>\n<\/tr>\n<tr>\n<td><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"8\" \/><\/td>\n<td bgcolor=\"#f2f2f2\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"4\" \/><\/td>\n<td align=\"center\" bgcolor=\"#f2f2f2\">\n<p><font><a target=\"_self\" href=\"http:\/\/www.eurekalert.org\/multimedia\/pub\/16451.php?from=143783\" rel=\"noopener noreferrer\"><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/multimedia\/pub\/rel\/16451_rel.jpg\" border=\"0\" \/><\/a><\/font><\/p>\n<p><font><a target=\"_self\" href=\"http:\/\/www.eurekalert.org\/multimedia\/pub\/16451.php?from=143783\" rel=\"noopener noreferrer\"><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/eutube\/icon_image_tiny.gif\" border=\"0\" \/><br \/>\n<span class=\"imagecaption\" style=\"color: black\"><b>IMAGEM:<\/b><\/span><\/a><br \/>\nDiagrama esquem\u00e1tico da experi\u00eancia de espalhamento de n\u00eautrons<span class=\"imagecaption\">.<\/span><br \/><\/font>\n<\/p>\n<p><font><span class=\"imagecaption\"><a target=\"_self\" href=\"http:\/\/www.eurekalert.org\/multimedia\/pub\/16451.php?from=143783\" rel=\"noopener noreferrer\">Cr\u00e9ditos e imagem ampliada.<\/a><\/span><\/font><\/p>\n<\/td>\n<td bgcolor=\"#f2f2f2\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"4\" \/><\/td>\n<td><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"8\" \/><\/td>\n<\/tr>\n<tr>\n<td><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"8\" \/><\/td>\n<td align=\"left\" bgcolor=\"#f2f2f2\" height=\"4\" valign=\"bottom\" width=\"4\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/corner_bl.jpg\" alt=\"\" border=\"0\" height=\"4\" width=\"4\" \/><\/td>\n<td bgcolor=\"#f2f2f2\" height=\"4\" width=\"202\"><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"10\" width=\"1\" \/><\/td>\n<td align=\"right\" bgcolor=\"#f2f2f2\" height=\"4\" valign=\"bottom\" width=\"4\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/corner_br.jpg\" alt=\"\" border=\"0\" height=\"4\" width=\"4\" \/><\/td>\n<td><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"1\" width=\"8\" \/><\/td>\n<\/tr>\n<tr>\n<td colspan=\"5\"><img decoding=\"async\" src=\"http:\/\/www.eurekalert.org\/images\/clear.gif\" alt=\"\" border=\"0\" height=\"10\" width=\"1\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><!-- End image here --><\/p>\n<p>A assinatura de um g\u00e1s feito desses monopolos foi igualmente observada, atrav\u00e9s do calor espec\u00edfico medido por  Bastian<br \/>\nKlemke (HZB), fornecendo mais uma confirma\u00e7\u00e3o da exist\u00eancia dos monopolos e demonstrando que estes interagem da mesma forma que as cargas el\u00e9tricas.<\/p>\n<p>No presente trabalho, os pesquisadores atestam, pela primeira vez, a exist\u00eancia de monopolos como estados emergentes da mat\u00e9ria &#8211;
