Asayansi achitapo kanthu popanga zida zamphamvu zomwe zimagwiritsa ntchito maginito popanga chofananira choyambirira chamitundu itatu chazinthu zotchedwa spin-ice.
一汽咱ayezi zozungulira ndizosazolowereka chifukwa zimakhala ndi zomwe zimatchedwa zolakwika zomwe zimakhala ngati mtengo umodzi wa maginito.
Maginito amodziwa, omwe amadziwikanso kuti maginito monopoles, kulibe m'chilengedwe;maginito onse akadulidwa pawiri nthawi zonse amapanga maginito atsopano okhala ndi pole ya kumpoto ndi kumwera.
Kwa zaka zambiri asayansi akhala akuyang'ana kutali ndi kutali kuti apeze umboni wa maginito omwe amapezeka mwachilengedwe ndi chiyembekezo chakuti potsirizira pake adzaika m'magulu amphamvu za chilengedwe mu zomwe zimatchedwa chiphunzitso cha chirichonse, ndikuyika physics yonse pansi pa denga limodzi.
Komabe, m’zaka zaposachedwapa akatswiri a sayansi ya zakuthambo akwanitsa kupanga maginito opangidwa ndi maginito opangidwa ndi maginito popanga zinthu zokhala ndi mbali ziwiri.
Mpaka pano mapangidwewa awonetsa bwino maginito monopole, koma n'zosatheka kupeza fiziki yomweyi pamene zinthuzo zimangokhala pa ndege imodzi.Zowonadi, ndi geometry yamitundu itatu ya spin-ice lattice yomwe ili yofunika kwambiri pakutha kwake kwachilendo kupanga tinthu tating'onoting'ono totengera maginito monopoles.
Pakafukufuku watsopano yemwe wafalitsidwa lero mu Nature Communications, gulu lotsogozedwa ndi asayansi ku Cardiff University apanga chofanizira choyambirira cha 3D cha zinthu zozungulira zozungulira pogwiritsa ntchito mtundu wapamwamba kwambiri wa 3D yosindikiza ndi kukonza.
Gululi likuti ukadaulo wosindikizira wa 3D wawalola kuti azitha kuwongolera geometry ya spin-ice, kutanthauza kuti amatha kuwongolera momwe maginito amapangidwira ndikusunthira mozungulira mumayendedwe.
Kutha kuwongolera maginito ang'onoang'ono amtundu wa 3D kumatha kutsegulira ntchito zambiri zomwe amati, kuyambira pakusungidwa kwamakompyuta mpaka kupanga makina apakompyuta a 3D omwe amatsanzira kapangidwe ka ubongo wamunthu.
"Kwa zaka zoposa 10 asayansi akhala akupanga ndi kuphunzira madzi oundana opangidwa ndi mitundu iwiri.Mwa kukulitsa machitidwe oterowo ku miyeso itatu timapeza chithunzi cholondola kwambiri cha spin-ice monopole physics ndipo timatha kuphunzira momwe zinthu zimakhudzira pamwamba, "anatero wolemba wamkulu Dr. Sam Ladak wochokera ku Cardiff University's School of Physics and Astronomy.
"Aka ndi koyamba kuti aliyense azitha kupanga mawonekedwe enieni a 3D a spin-ice, mwa kapangidwe kake, pa nanoscale."
Makina opangira oundana adapangidwa pogwiritsa ntchito njira zamakono za 3D nanofabrication momwe ma nanowires ang'onoang'ono adasanjikizidwa m'magulu anayi amtundu wa lattice, womwewo umayeza osakwana utali wa tsitsi la munthu.
Mtundu wapadera wa maikrosikopu womwe umadziwika kuti maginito mphamvu yamagetsi, yomwe imakhudzidwa ndi maginito, idagwiritsidwa ntchito kuwonetsa maginito amagetsi omwe amapezeka pa chipangizocho, kulola gululo kuyang'anira kayendedwe ka maginito amtundu umodzi kudutsa mawonekedwe a 3D.
"Ntchito yathu ndi yofunika chifukwa imasonyeza kuti makina osindikizira a nanoscale 3D angagwiritsidwe ntchito kutsanzira zipangizo zomwe nthawi zambiri zimapangidwira pogwiritsa ntchito chemistry," anapitiriza Dr. Ladak.
"Pamapeto pake, ntchitoyi ikhoza kupereka njira yopangira zida zatsopano zamaginito, pomwe zinthu zakuthupi zimasinthidwa ndikuwongolera 3D geometry ya lattice yokumba.
“Zipangizo zosungira maginito,硬盘drive kapena maginito ofikira mwachisawawa, ndi gawo lina lomwe lingakhudzidwe kwambiri ndi izi.Monga momwe zida zamakono zimagwiritsa ntchito miyeso iwiri yokha mwa itatu yomwe ilipo, izi zimachepetsa kuchuluka kwa chidziwitso chomwe chingasungidwe.Popeza ma monopoles amatha kusunthidwa mozungulira 3D lattice pogwiritsa ntchito maginito, zitha kukhala zotheka kupanga chosungira chenicheni cha 3D potengera maginito.
