Ososayensi bathathe isinyathelo esiya ekudalweni kwamadivayisi anamandla asebenzisa amandla kazibuthe ngokudala ikhophi yokuqala yezinhlangothi ezintathu yento eyaziwa ngokuthi i-spin-ice.
I-spin ice materials ayijwayelekile kakhulu njengoba inalokho okubizwa ngokuthi 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 ukuze bathole ubufakazi bama-monopole kazibuthe avela ngokwemvelo ngethemba lokuthi ekugcineni bahlanganise amandla ayisisekelo emvelo abe yilokho okubizwa ngokuthi inkolelo-mbono yakho konke, babeke 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 ye-spin-ice lattice eyisihluthulelo sekhono layo elingajwayelekile lokudala izakhiwo ezincane ezilingisa ama-monopole kazibuthe.
Ocwaningweni olusha olushicilelwe namuhla ku-Nature Communications, ithimba eliholwa ososayensi baseNyuvesi yaseCardiff lenze umfanekiso wokuqala owake waba yi-3D wezinto ezisetshenziswayo zeqhwa zisebenzisa 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 kwekhompyutha okuthuthukisiwe kuye 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 idalwe kusetshenziswa amasu esimanjemanje e-3D nanofabrication lapho ama-nanowires amancane ayenqwabelene ezingqimbeni ezine esakhiweni se-lattice, sona ngokwaso esikala ngaphansi kobubanzi bezinwele zomuntu sezizonke.
Uhlobo olukhethekile lwe-microscopy olwaziwa nge-magnetic force microscopy, oluzwela kukazibuthe, lwabe selusetshenziselwa ukubona ngeso lengqondo amanani kazibuthe akhona kudivayisi, okuvumela ithimba ukuthi lilandelele ukunyakaza komazibuthe abanesigxobo esisodwa kusakhiwo se-3D.
“Umsebenzi wethu ubalulekile njengoba ubonisa ukuthi ubuchwepheshe bokuphrinta 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.
