Ososayensi bathathe igxathu eliya ekudalweni kwamadivayisi anamandla ahlanganisaumgcanjethi ukushaja ngokwakha i-replica yokuqala enobumbano emithathu yezinto ezibonakalayo ezaziwa ngokuthi i-spin-ice.
Izinsiza ze-Spin Ice zingajwayelekile kakhulu njengoba zinazo okuthiwa yiziphambeko eziziphatha njengesigxobo esisodwa sozibuthe.
Lawa ma-pole magnets angashadile, owaziwa nangokuthi ama-monopoles kazibuthe, awekho emvelweni; Lapho zonke izinto zikamabuthentshi zisikwa zibe ezimbili kuzohlala zidala uzibuthe omusha ngeNorth POLE neNingizimu.
Kwaphela amashumishumi eminyaka ososayensi bebelokhu bebukeka benobufakazi bokuthi kwenzeka ngokwemveloumgcanjethi I-Monopoles ethembeni lokugcina ihlela amabutho ayisisekelo emvelo ibe yi-theory yayo yonke into, ukubeka yonke i-physics ngaphansi kophahla olulodwa.
Kodwa-ke, engcupheni yeminyaka yamuva nje bakwazile ukukhiqiza izinhlobo zokufakelwa ze-monopole kazibuthe ngokudalwa kwezinto ezinama-spin-ice ahlukahlukene.
Kuze kube manje lezi zinhlaka zibonise ngempumelelo i-monopole kazibuthe, kepha akunakwenzeka ukuthola i-physics efanayo lapho okuqukethwe kuvalelwe endizeni eyodwa. Ngempela, yi-geometry eqondile enezici ezintathu ye-spin-ice lattice okuyisihluthulelo sayo esingajwayelekile sokwakha izakhiwo ezincane ezilingisaumgcanjethimonopoles.
Ocwaningweni olusha olushicilelwe namhlanje ekuxhumaneni kwemvelo, iqembu eliholwa ososayensi eCardiff University badale umfanekiso wokuqala we-3D we-spin-ice prespite esebenzisa i-3D Prance and Processing.
Iqembu lithi ubuchwepheshe bokuphrinta we-3D ubavumele ukuthi bavumelane nejometri ye-spin-ice-ice, okusho ukuthi bakwazi ukulawula indlela ama-monopoles kazibuthe akhiwa futhi ahanjiswa ngayo ezinhlelweni.
Ukwazi ukukhohlisa ama-moniole ama-moniopole mini ku-3D angavula wonke ama-application azonke athi, kusuka kwisitoreji sekhompyutha esithuthukisiwe ekwakhiweni kwamanethiwekhi wekhompyutha we-3D alingisa ukwakheka kobuchopho bomuntu.
"Eminyakeni engaphezu kwe-10 ososayensi bebelokhu bedala futhi befunda iqhwa le-spin-ice ngobukhulu obukhulu. Ngokwengeza lezo zinhlelo kuya kwezintathu - amanani amathathu sithola ukumelwa okunembe kakhudlwana kwe-spin-ice monopole physics futhi bayakwazi ukutadisha umthelela we-surfaces, "kusho umlobi we-lead uDkt Sam Ladak wase-physic yunivesithi ye-physics.
"Kungokokuqala ukuthi noma ngubani akwazile ukudala i-replica eqondile ye-3D ye-spin-ice, ngokuqamba, kwi-nanoscale."
I-Spin-Ice-Ice yenziwe yakhiwa kusetshenziswa amasu we-State-of-the-art 3D nanofabrication lapho ama-nanomayi amancane ayefakwe khona abe izingqimba ezine ekwakhiweni kwamathanga, okwakulinganiswa ngaphansi kobubanzi bezinwele zomuntu.
Uhlobo olukhethekile lwe-microscopy owaziwa ngokuthi ama-microscopy ama-microscopy, azwela ubusika, abese esetshenziselwa ukubona ngeso lengqondo amacala amabuthe akhona kudivayisi, avumele iqembu ukuthi lilandele ukunyakaza kwezibalo ze-single-pole.
"Umsebenzi wethu ubalulekile ngoba kukhombisa ukuthi ubuchwepheshe bokunyathelisa kweNanoscale 3D bungasetshenziselwa ukulingisa izinto ezivame ukuguqulwa nge-chemistry," kuqhubeka uDkt Ladak.
"Ekugcineni, lo msebenzi unganikeza izindlela zokukhiqiza i-novel magnetic metamaants, lapho impahla yezinto ezibonakalayo ihlelwe ngokulawula i-3D geometry ye-lattice yokufakelwa.
"Amadivayisi wesitoreji sasolwandle, afana ne-hard disk drive noma amadivaysi wememori yokufinyelela kazibuthe, kungenye indawo ebingaba nomthelela omkhulu ngaleli mpumelelo. Njengoba amadivaysi akhona asebenzisa kuphela ama-Divensions amabili kuphela atholakalayo, lokhu kunciphisa inani lolwazi olungagcinwa. Njengoba ama-monopoles angahanjiswa ezungeze i-3D lattice esebenzisa amandla kazibuthe kungenzeka ukudala idivaysi yesitoreji eyi-3D esekelwe kumakhi kazibuthe. "
