Ua hana ka poʻe ʻepekema i ka hana ʻana i nā mea ikaika e hoʻohana aimākia hoʻopiʻi ma ka hana ʻana i ke kope ʻekolu-dimensional mua loa o kahi mea i ʻike ʻia he spin-ice.
He mea ʻokoʻa loa nā mea hau milo no ka mea, loaʻa iā lākou nā mea i kapa ʻia nā hemahema e like me ke kia hoʻokahi o ka magnet.
ʻO kēia mau mākia mākia hoʻokahi, i ʻike ʻia hoʻi he monopoles magnetic, ʻaʻohe mea i ke ʻano;ke ʻoki ʻia kēlā me kēia mea magnetic i ʻelua, e hana mau ia i kahi magnet hou me ka ʻākau a me ka pou hema.
No nā makahiki he nui ke ʻimi nei ka poʻe ʻepekema i nā hōʻike o ke ʻano kūlohelohemākia monopoles i ka manaʻolana e hoʻohui hope i nā mana kumu o ke ʻano i kahi i kapa ʻia ʻo ka manaʻo o nā mea a pau, e waiho ana i nā physics āpau ma lalo o ka hale hoʻokahi.
Eia nō naʻe, i nā makahiki i hala iho nei, ua hoʻokō ka poʻe physicists i ka hana ʻana i nā mana hana o kahi monopole magnetic ma o ka hana ʻana i nā mea ʻelua-dimensional spin-ice.
I kēia lā, ua hōʻike maikaʻi kēia mau hale i kahi monopole magnetic, akā ʻaʻole hiki ke loaʻa ka physics like ke hoʻopaʻa ʻia ka mea i ka mokulele hoʻokahi.ʻOiaʻiʻo, ʻo ia ka geometry kikoʻī ʻekolu-dimensional o ka lattice spin-ice ka mea nui i kona hiki ʻole ke hana i nā hale liʻiliʻi e like memākiamonopoles.
Ma kahi noiʻi hou i paʻi ʻia i kēia lā ma Nature Communications, ua hana kahi hui i alakaʻi ʻia e nā ʻepekema ma ke Kulanui ʻo Cardiff i ka hoʻopiʻi 3D mua loa o kahi mea spin-ice me ka hoʻohana ʻana i kahi ʻano paʻi 3D a me ka hana ʻana.
Wahi a ka hui, ua ʻae ka ʻenehana paʻi 3D iā lākou e hoʻolikelike i ke ʻano o ka hau milo i hana ʻia, ʻo ia hoʻi, hiki iā lākou ke hoʻomalu i ke ʻano o ka hoʻokumu ʻia ʻana a me ka neʻe ʻana o nā monopoles magnetic i nā ʻōnaehana.
ʻO ka hiki ke hoʻopololei i nā mini monopole magnets ma 3D hiki ke wehe i ka lehulehu o nā noi a lākou e ʻōlelo ai, mai ka hoʻonui ʻia ʻana o ka mālama kamepiula a hiki i ka hana ʻana i nā ʻupena helu 3D e hoʻohālike i ke ʻano neural o ka lolo kanaka.
"No nā makahiki he 10 i hana a aʻo ʻia nā ʻepekema ʻepekema i nā ʻāpana ʻelua.Ma ka hoʻonui ʻana i ia ʻōnaehana i nā ʻāpana ʻekolu, loaʻa iā mākou kahi hōʻike pololei loa o ka spin-ice monopole physics a hiki iā mākou ke aʻo i ka hopena o nā ʻili, "wahi a ka mea kākau alakaʻi ʻo Dr. Sam Ladak mai ke kula ʻo Cardiff University's School of Physics and Astronomy.
"ʻO kēia ka manawa mua i hiki i kekahi ke hana i kahi kope 3D pololei o kahi spin-ice, ma ka hoʻolālā ʻana, ma ka nanoscale."
Ua hoʻokumu ʻia ka hau milo i hana ʻia me ka hoʻohana ʻana i nā ʻenehana nanofabrication 3D i hoʻopaʻa ʻia i nā nanowires liʻiliʻi i ʻehā mau papa i loko o kahi hoʻolālā lattice, ʻo ia ka mea i ana ʻia ma mua o ka laulā o ka lauoho kanaka.
Ua hoʻohana ʻia kahi ʻano microscopy kūikawā i kapa ʻia ʻo magnetic force microscopy, kahi mea maʻalahi i ka magnetism, a laila ua hoʻohana ʻia e ʻike i nā koina magnetic i loaʻa ma luna o ka hāmeʻa, e ʻae ana i ka hui e nānā i ka neʻe ʻana o nā pole hoʻokahi ma waena o ka hale 3D.
"He mea koʻikoʻi kā mākou hana ma muli o ka hōʻike ʻana e hiki ke hoʻohana ʻia nā ʻenehana paʻi nanoscale 3D e hoʻohālike i nā mea i hana maʻamau ʻia ma o ke kemika," i hoʻomau ai ʻo Kauka Ladak.
"ʻO ka hope loa, hiki i kēia hana ke hāʻawi i kahi ala e hana ai i nā metamaterial magnetic novel, kahi i hoʻopaʻa ʻia ai nā waiwai waiwai ma ka kāohi ʻana i ka geometry 3D o kahi lattice artificial.
"ʻO nā mea mālama magnetic, e like me ka hard disk drive a i ʻole nā mea hoʻomanaʻo hoʻomanaʻo magnetic random access, kahi wahi ʻē aʻe i hiki ke hoʻopilikia nui ʻia e kēia hanana.Ke hoʻohana nei nā mea hana o kēia manawa i ʻelua wale nō o nā ana ʻekolu i loaʻa, e kaupalena kēia i ka nui o ka ʻike i hiki ke mālama ʻia.No ka mea hiki ke hoʻoneʻe ʻia nā monopoles a puni ka lattice 3D me ka hoʻohana ʻana i kahi māla magnetic hiki paha ke hana i kahi mea mālama 3D maoli e pili ana i ka uku magnetic.
