Masayendisiti atora danho rekugadzira zvishandiso zvine simba zvinoshandisamagineti kuchaja nekugadzira kopi yekutanga yezvinhu zvine mativi matatu inozivikanwa sespin-ice.
Zvinhu zvechando zvinotenderera hazviwanzoitiki sezvo zvine zvikanganiso zvinonzi zvinoita sedanda rimwe chete remagineti.
Magineti aya epaburi rimwe chete, anozivikanwawo semagineti monopoles, haapo muzvisikwa; kana chinhu chega chega chegineti chikachekwa kuita maviri, chinogara chichigadzira magineti matsva ane kuchamhembe nekuchamhembe.
Kwemakumi emakore masayendisiti anga achitsvaga humbowo hwekuti zvinhu zvinoitika nenzira yechisikigomagineti mamonopoles netariro yekupedzisira yekubatanidza masimba makuru ezvisikwa kuita inonzi dzidziso yezvinhu zvese, vachiisa fizikisi yese pasi pedenga rimwe chete.
Zvisinei, mumakore achangopfuura nyanzvi dzefizikisi dzakakwanisa kugadzira mhando dzekugadzira dzemonopole yemagineti kuburikidza nekugadzira zvinhu zve spin-ice zvine mativi maviri.
Kusvika pari zvino, maumbirwo aya akabudirira kuratidza monopole yemagineti, asi hazvigoneke kuwana fizikisi imwechete kana zvinhu zvacho zvakavharirwa mundege imwe chete. Zvechokwadi, ndiyo geometry chaiyo yemativi matatu e spin-ice lattice ndiyo inokosha pakukwanisa kwayo kugadzira maumbirwo madiki anotevedzeramaginetimapori maviri.
Muchidzidzo chitsva chakaburitswa nhasi muNature Communications, timu inotungamirwa nemasayendisiti kuCardiff University vakagadzira kopi yekutanga ye3D yezvinhu zvinogadzirwa nechando vachishandisa mhando yepamusoro yekudhinda nekugadzirisa kwe3D.
Chikwata ichi chinoti tekinoroji yekudhinda ye3D yakavabvumira kugadzirisa maitiro ekugadzira chando chekugadzira, zvichireva kuti vanogona kudzora magadzirirwo uye kufamba kwemamonopole emagineti mumasisitimu.
Kukwanisa kushandisa magineti madiki emonopole mu3D kunogona kuvhura maapplication akawanda avanoti, kubva pakuchengetera makomputa kwakawedzerwa kusvika pakugadzirwa kwema network e3D computing anotevedzera chimiro chetsinga dzeuropi hwemunhu.
"Kwemakore anopfuura gumi masayendisiti anga achigadzira nekudzidza nezve artificial spin-ice muzvikamu zviviri. Nekuwedzera masisitimu akadaro kusvika pazvikamu zvitatu tinowana mufananidzo wakarurama we spin-ice monopole physics uye tinokwanisa kudzidza kukanganiswa kwenzvimbo," akadaro munyori mukuru Dr. Sam Ladak wekuCardiff University's School of Physics and Astronomy.
"Iyi ndiyo nguva yekutanga kuti chero munhu akwanise kugadzira kopi chaiyo ye3D yespin-ice, nekugadzirwa kwayo, pa nanoscale."
Aizi yekugadzirwa yakagadzirwa uchishandisa matekiniki emhando yepamusoro e3D nanofabrication umo waya diki dzenano dzakaiswa muzvikamu zvina muchimiro che lattice, icho pachacho chaive chisingasviki upamhi hwebvudzi remunhu.
Rudzi rwakakosha rwe microscopy runozivikanwa se magnetic force microscopy, iyo inonzwa magnetism, rwakazoshandiswa kuona ma magnetic charges aripo pamudziyo, zvichibvumira timu kuti itevere kufamba kwema magnets ane pole imwe chete muchimiro che3D.
"Basa redu rakakosha sezvo richiratidza kuti matekinoroji ekudhinda e3D ane nanoscale anogona kushandiswa kutevedzera zvinhu zvinowanzogadzirwa kuburikidza nekemikari," vakaenderera mberi Dr. Ladak.
"Pakupedzisira, basa iri rinogona kupa nzira yekugadzira zvinhu zvitsva zvemagineti, uko hunhu hwezvinhu hunogadziriswa nekudzora 3D geometry ye lattice yekugadzira."
"Zvishandiso zvekuchengetedza magineti, zvakaita sedhisiki redhisiki kana magnetic random access memory devices, ndeimwe nzvimbo inogona kukanganiswa zvikuru nekubudirira uku. Sezvo zvishandiso zviripo zvinoshandisa zviyero zviviri chete kubva pazvitatu zviripo, izvi zvinoderedza huwandu hweruzivo runogona kuchengetwa. Sezvo mamonopoles achigona kutamiswa achitenderedza 3D lattice uchishandisa simba remagineti, zvinogona kugadzirwa mudziyo wekuchengetedza we3D chaiwo zvichibva pakuchaja kwemagineti."
