Asayansi achitapo kanthu popanga zida zamphamvu zomwe zimalumikizamaginito perekani ndalama popanga chofaniziro choyambirira cha mbali zitatu cha chinthu chodziwika kuti spin-ice.
Zida za ayezi zozungulira ndizosazolowereka chifukwa zili 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 wosonyeza kuti zimachitika mwachilengedwemaginito ma monopoles ndi chiyembekezo chomaliza kuyika magulu amphamvu achilengedwe mu chiphunzitso chotchedwa chiphunzitso cha chilichonse, ndikuyika fiziki 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 ting'onoting'ono tomwe timatengera.maginitomonopoles.
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 wosindikiza ndi kukonza.
Gululi likuti ukadaulo wosindikizira wa 3D wawalola kuti azitha kuwongolera geometry ya spin-ice, kutanthauza kuti amatha kuwongolera momwe maginito amapangidwira ndikuyendayenda m'machitidwe.
Kutha kuwongolera maginito ang'onoang'ono a 3D kutha kutsegulira mapulogalamu ambiri omwe amati, kuyambira pakusungidwa kwamakompyuta mpaka kupanga ma network a 3D computing omwe amatsanzira kapangidwe ka ubongo wamunthu.
"Kwa zaka zopitirira 10 asayansi akhala akupanga ndi kuphunzira madzi oundana opangidwa m'njira ziwiri.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 tinthu tating'onoting'ono tomwe timatulutsa timadzi tating'onoting'ono tating'onoting'ono tating'onoting'ono tidasanjikizidwa m'magawo anayi amtundu wa lattice, womwewo womwe umayeza utali wonse 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 kayendetsedwe ka maginito amtundu umodzi kudutsa dongosolo la 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, monga hard disk 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.
