Asayansi achitapo kanthu popanga zida zamphamvu zomwe zimagwiritsa nchito maginito popanga chofananira chyambirira chamitundu itatu chazinthzotchedwa spin-ice。
Zida za ayezi zozungulira and dizzosazoloereka chifukwa zimakhala and di zomwe zimatchedwa zolakwika zomwe zimakhala ngati mtengo ummodzi是maginito。
Maginito amodziwa, omwe amadziwikanso kuti Maginito monopoles, kulibe m' chilgedwe; Maginito onse akadulidwa pairi nthawi zone, amapanga Maginito atsopano okhala, i pole ya kumpoto ndi kumwera。
Kwa zaka zambiri asayansi akhala kuuyang 'ana kutali ndi kutali kutali kutali apeze umboni was maginito omwe amapezeka mwachilengegei ndi chiyememeczo chakuti potsirizira pakake adzaika m'magulu amphamvu za chilengedwe mu zomwe zimatchedwa chiphunzitso cha chirichonse, ndikuyika物理yonse panansi pa enga limodzi。
Komabe, m 'zaka zaposachedawa akatswiri, a sayansi ya zakuthambo akwanitsa kupanga maginito opangidwa和di maginito popanga zinthu zokhala和i mbali ziwiri。
Mpaka pano mapangidwewa awonetsa是一个磁单极子，koma n'zosatheka kupeza fiziki yomwei pamene zinthuzo zimangokhala pa ndege imodzi。Zowonadi, and i geometry yamitundu itatu ya自旋冰晶格yomwe i yofunika kwambiri pakutha kwake kwachilendo kupanga tinthting ' onnoting ' totengera maginito单极子。
Pakafukufuku watsopano yemwe wafalitsidwa lero mu Nature Communications, gulu lotsogozedwa和di asayanku ku aganga chofanizira choyambirira 3D cha zinthu zozungulira zozungulira pogwiritsa nchito mtundu wapamwamba kwambiri 3D yosindikizza和di kukonza。
Gululi likuti ukadaulo wosindikizira wa 3D wawalola kuti azitha kuwongolera几何图形ya自旋冰，kutanthauza kuti amatha kuwongolera momwe maginito amapangidwira ndikusunthira mozungulira mumayendwe。
Kutha kuwongolera maginito ang'onoang'ono amtundu是3D kumatha kutsegulira nchito zambiri zomwe amati, kuyambira pakusungidwa kwamakompyuta mpaka kupanga makina apakompyuta 3D omwe amatsanzira kapangidwe ka ubongo wamunthu。
Kwa zaka zoposa 10 asayansi akhala akupanga ndi kuphunzira madzi oundana opangidwa ndi mitundu iwiri。Mwa kukulitsa machittiwe oterowo ku miyeso itatu timapeza chithunzi cholondola kwambiri cha自旋冰单极子物理学ndipo timatha kuphunzira momwe zinthu zimakhudzira pamwamba, anatero wolemba wamkulu博士来自卡迪夫大学物理与天文学院。
“又名ndi koyamba kuti aliyense azitha kupanga mawonee，我们的3D旋转冰，mwa kapangidwe蛋糕，纳米级。”
Makina opangira oundana adapangidwa pogwiritsa nchito njira zamakono za 3D纳米制造momwe ma纳米线ang' onoango 'ono adasanjikizidwa m'magulu anayi amtundu晶格，womwewo umayeza osakwana utali wa tsitsi la munthu。
Mtundu wapadera wa maikrosikopu womwe umadziwika kuti maginito imhamvu yamagetsi, yomwe imakhudzidwa ndi maginito, idagwiritsidwa nchito kuwonetsa magmagetsi omwe amapezeka pa chipangizocho, kulola gululo kuyang'anira kayendedwe ka maginito amtundu ummodzi kudutsa mawonedwe a 3D。
“nchito yathu ndi yofunika chifukwa imasonyeza kuti makina osindikizira是纳米级三维血管结构，我们nchito kutsanzira zipangizo zomwe nthawi zambiri zimapangidwira pogwiritsa nchito chemistry，”apitriza Ladak博士说。
“Pamapeto pake, nchitoyi ikhoza kupereka njira yopangira zatsopano zamaginito, pomwe zinthu zakuthupi zimasinthidwa ndikuwongolera三维几何图形ya lattice yokumba。
“Zipangizo zosungira maginito, monga硬盘驱动器kapena maginito ofikira mwachiswawa, and di gawo lina lomwe lingakhudzidwe kwambiri ndi izi”。蒙古妈妈zida zamakono zimagwirita nchichito miyeso iwiritya yomititu yomi ilipo, izi zimachepetsa kuchuluka kwa chidziziwitso chomwe chingasgidwe。Popeza ma monopoles amatha kusunthidwa mozungulila 3D lattice pogwiritsa nchito maginito, zitha kukhala zotheka kupanga chosungira chenicheni cha 3D potentigera maginito。
