Izazinzulu zithathe inyathelo elisingise ekudalweni kwezixhobo ezinamandla ezisebenzisa amandla emagnethi ngokwenza ireplica yokuqala enobude obuthathu bemathiriyeli eyaziwa ngokuba yi-spin-ice.
Izixhobo zomkhenkce ezijikelezayo aziqhelekanga kakhulu njengoko zinento ebizwa ngokuba ziziphene eziziphatha njengepali enye yemagnethi.
Ezi magnethi zepali enye, ezaziwa ngokuba ziimonopole zemagnethi, azikho kwindalo;xa yonke imathiriyeli yemagnethi isikwa kubini iya kuhlala idala umazibuthe omtsha onepali esemantla nasezantsi.
Kangangamashumi eminyaka izazinzulu zijonge kude nakude zikhangela ubungqina bendalo bemagnethi monopoles ngethemba lokuba ekugqibeleni badibanise amandla asisiseko endalo kwinto ebizwa ngokuba yithiyori yayo yonke into, ibeka yonke ifiziksi phantsi kophahla olunye.
Nangona kunjalo, kwiminyaka yakutshanje iingcali zefiziksi ziye zakwazi ukuvelisa iinguqulelo ezenziweyo zemagnethi ye-monopole ngokudala izinto ezimacala amabini ajikeleze umkhenkce.
Ukuza kuthi ga ngoku ezi zakhiwo zibonise ngempumelelo i-monopole yamagnetic, kodwa akunakwenzeka ukufumana i-physics efanayo xa izinto zivalelwe kwindiza enye.Inene, yijiyometri ye-spin-ice lattice engundoqo kubuchule bayo obungaqhelekanga bokudala izakhiwo ezincinci ezilinganisa iimonopole zemagnethi.
Kuphononongo olutsha olupapashwe namhlanje kuNxibelelwano lweNdalo, iqela elikhokelwa zizazinzulu kwiYunivesithi yaseCardiff lenze umfanekiso wokuqala we-3D wesixhobo se-spin-ice usebenzisa uhlobo oluntsonkothileyo lwe-3D yoshicilelo kunye nokucubungula.
Iqela lithi iteknoloji yoshicilelo ye-3D ibavumele ukuba balungelelanise ijometri ye-artificial spin-ice, oku kuthetha ukuba banokulawula indlela i-monopoles yamagnetic eyenziwe ngayo kwaye ijikeleze kwiinkqubo.
Ukukwazi ukukhohlisa imagnethi encinci ye-monopole kwi-3D kunokuvula yonke inkitha yezicelo abazithethayo, ukusuka kugcino oluphuculweyo lwekhompyuter ukuya ekudalweni kothungelwano lwekhompyuter lwe-3D olulinganisa ubume be-neural bobuchopho bomntu.
Ngaphezu kweminyaka eli-10 izazinzulu bezisenza kwaye zifunda umkhenkce owenziweyo kumacala amabini.Ngokwandisa iinkqubo ezinjalo ukuya kumacala amathathu sifumana ukumelwa okuchaneke ngakumbi kwe-spin-ice monopole physics kwaye siyakwazi ukufunda impembelelo yomphezulu,” watsho umbhali okhokelayo uGqr. Sam Ladak ovela kwiSikolo seFiziksi kunye neNkwenkwezi yeYunivesithi yaseCardiff.
"Eli sisihlandlo sokuqala ukuba nabani na akwazi ukwenza umfanekiso ochanekileyo we-3D we-spin-ice, ngoyilo, kwi-nanoscale."
Umkhenkce owenziweyo wadalwa kusetyenziswa iindlela zangoku ze-3D ze-nanofabrication apho ii-nanowires ezincinci zafakwa kumaleko amane kwi-lattice structure, yona ngokwayo eyayilinganisa ngaphantsi kobubanzi beenwele zomntu xa iyonke.
Uhlobo olukhethekileyo lwemakroskopu eyaziwa ngokuba yimagnethi yamandla imakroskopu, enovakalelo kwimagnethi, emva koko yasetyenziselwa ukubona intlawulo kazibuthe ekhoyo kwisixhobo, ivumela iqela ukuba lilandele umkhondo wentshukumo yemagnethi enepali enye kwisakhiwo se-3D.
"Umsebenzi wethu ubalulekile kuba ubonisa ukuba i-nanoscale 3D technologies yokushicilela ingasetyenziselwa ukulinganisa izinto ezivame ukuhlanganiswa nge-chemistry," waqhubeka uDkt Ladak.
"Ekugqibeleni, lo msebenzi unokubonelela ngeendlela zokuvelisa i-metamatariyali zemagneti, apho iipropathi zezinto eziphathekayo zilungelelaniswa ngokulawula i-3D geometry yelatisi eyenziweyo.
“Izixhobo zogcino zemagnethi, ezinje nge-hard disk drive okanye izixhobo zememori yokufikelela okungahleliweyo, yenye indawo enokuchatshazelwa kakhulu yile mpumelelo.Njengoko izixhobo zangoku zisebenzisa imilinganiselo emibini kuphela kwemithathu ekhoyo, oku kunciphisa ubungakanani bolwazi olunokugcinwa.Kuba iimonopoles zinokuhanjiswa zijikeleze i-3D lettice kusetyenziswa imagnethi kunokwenzeka ukwenza isixhobo sokugcina se-3D esekwe kwintlawulo yemagnethi.
