Ososayensi bathathe igxathu eliya ekwakhiweni kwemishini enamandla ebophayokazibuthe khokhisa ngokudala isifaniso sokuqala sezinhlangothi ezintathu sento eyaziwa ngokuthi i-spin-ice.
I-spin ice materials ayijwayelekile kakhulu njengoba inalokho okuthiwa yiziphambeko ezisebenza njengesigxobo esisodwa sikazibuthe.
Lezi zibuthe zesigxobo esisodwa, ezaziwa nangokuthi ama-monopole kazibuthe, abekho emvelweni;lapho zonke izinto kazibuthe zisikwa zibe ezimbili ziyohlala zenza uzibuthe omusha onesigxobo esisenyakatho naseningizimu.
Sekungamashumi eminyaka ososayensi bebheka kude nakude ukuthola ubufakazi bokwenzeka ngokwemvelokazibuthe ama-monopoles ngethemba lokuthi ekugcineni ahlanganise amandla ayisisekelo emvelo abe yilokho okubizwa ngokuthi inkolelo-mbono yakho konke, ukubeka yonke i-physics ngaphansi kophahla olulodwa.
Kodwa-ke, eminyakeni yamuva izazi zefiziksi ziye zakwazi ukukhiqiza izinguqulo zokwenziwa ze-monopole kazibuthe ngokudala izinto ze-spin-ice ezinezinhlangothi ezimbili.
Kuze kube manje lezi zakhiwo zibonise ngempumelelo i-monopole kazibuthe, kodwa akunakwenzeka ukuthola i-physics efanayo lapho impahla ivalelwe endizeni eyodwa.Ngempela, i-geometry ethize enezinhlangothi ezintathu ze-spin-ice lattice eyisihluthulelo sekhono layo elingajwayelekile lokudala izakhiwo ezincane ezilingisayo.kazibutheama-monopoles.
Ocwaningweni olusha olushicilelwe namuhla ku-Nature Communications, ithimba eliholwa ososayensi eNyuvesi yaseCardiff lenze umfanekiso wokuqala owake waba yi-3D wempahla ye-spin-ice lisebenzisa uhlobo oluyinkimbinkimbi lokuphrinta nokucutshungulwa kwe-3D.
Ithimba lithi ubuchwepheshe bokuphrinta be-3D bubavumele ukuthi balungise i-geometry ye-spin-ice yokwenziwa, okusho ukuthi bangakwazi ukulawula indlela ama-monopole azibuthe akhiwa ngayo futhi azulazule ezinhlelweni.
Ukwazi ukusebenzisa omazibuthe abancane be-monopole ku-3D kungavula inqwaba yezinhlelo zokusebenza abazishoyo, kusukela ekugcinweni okuthuthukisiwe kwekhompyutha kuya ekwakhiweni kwamanethiwekhi ekhompyutha e-3D alingisa isakhiwo se-neural sobuchopho bomuntu.
“Sekuyiminyaka engaphezu kwe-10 ososayensi bedala futhi befunda i-spin-ice yokwenziwa ngezindlela ezimbili.Ngokunweba lezi zinhlelo zibe izinhlangothi ezintathu sithola ukumelela okunembe kakhudlwana kwe-spin-ice monopole physics futhi siyakwazi ukufunda umthelela wendawo,” kusho umlobi oholayo uDkt. Sam Ladak waseCardiff University’s School of Physics and Astronomy.
"Kungokokuqala ngqa ukuthi noma ubani akwazi ukwenza umfanekiso oqondile we-3D we-spin-ice, ngokuklama, ku-nanoscale."
I-spin-ice yokwenziwa yadalwa kusetshenziswa amasu esimanjemanje e-3D nanofabrication lapho ama-nanowires amancane ayenqwabelene abe yizendlalelo ezine esakhiweni se-lattice, sona ngokwaso esikala ngaphansi kobubanzi bezinwele zomuntu sezizonke.
Uhlobo olukhethekile lwe-microscopy olwaziwa nge-magnetic force microscopy, oluzwela kukazibuthe, lwabe selusetshenziswa ukuze kubonwe ngeso lengqondo amanani kazibuthe akhona kudivayisi, okuvumela iqembu ukuthi lilandelele ukunyakaza komazibuthe abanesigxobo esisodwa kusakhiwo se-3D.
“Umsebenzi wethu ubalulekile njengoba ubonisa ukuthi ubuchwepheshe bokunyathelisa be-nanoscale 3D bungasetshenziswa ukulingisa izinto ezivame ukuhlanganiswa nge-chemistry,” kuqhuba uDkt. Ladak.
“Ekugcineni, lo msebenzi unganikeza indlela yokukhiqiza ama-metamatadium anoveli kazibuthe, lapho izakhiwo ezibonakalayo zishunwa ngokulawula i-3D geometry ye-lattice yokwenziwa.
“Izisetshenziswa zikamagnetic zokugcina, njenge-hard disk drive noma izisetshenziswa kazibuthe zenkumbulo yokufinyelela okungahleliwe, kungenye indawo engase ibe nomthelela omkhulu kulokhu kuphumelela.Njengoba izisetshenziswa zamanje zisebenzisa izilinganiso ezimbili kuphela kwezintathu ezitholakalayo, lokhu kukhawulela inani lolwazi olungagcinwa.Njengoba ama-monopoles anganyakaziswa eduze kwe-lattice ye-3D kusetshenziswa inkambu kazibuthe kungase kwenzeke ukwakha idivayisi ye-3D yangempela yesitoreji ngokusekelwe ekushajweni kazibuthe.
