Abashakashatsi babonye imyitwarire mishya idasanzwe mugihe ibintu bya rukuruzi byashyutswe.Iyo ubushyuhe buzamutse, magnetiki azunguruka muri ibi bikoresho "arakonja" muburyo buhagaze, ubusanzwe bibaho iyo ubushyuhe bugabanutse.Abashakashatsi bashyize ahagaragara ibyo babonye mu kinyamakuru Nature Physics.
Abashakashatsi basanze iki kintu mubikoresho bya neodymium.Mu myaka mike ishize, basobanuye iki kintu "kwizana kwizunguruka".Ikirahure kizunguruka mubisanzwe ni icyuma kivanze, kurugero, atome yicyuma ivangwa muburyo butemewe na gride ya atome y'umuringa.Buri atome y'icyuma ni nka rukuruzi ntoya, cyangwa kuzunguruka.Ibi byateganijwe bizunguruka byerekanwe muburyo butandukanye.
Bitandukanye nikirahure gakondo kizunguruka, kivanze kubushake nibikoresho bya magneti, neodymium nikintu.Mugihe hatabayeho ikindi kintu icyo aricyo cyose, cyerekana imyitwarire ya vitrification muburyo bwa kristu.Kuzenguruka bikora uburyo bwo kuzunguruka nka spiral, bikaba bidasanzwe kandi bigahora bihinduka.
Muri ubu bushakashatsi bushya, abashakashatsi basanze iyo bashyushya neodymium kuva kuri -268 ° C kugeza kuri -265 ° C, kuzunguruka kwayo "gukonjesha" mu buryo bukomeye, bikora magneti ku bushyuhe bwo hejuru.Nkuko ibikoresho bikonje, uburyo bwo kuzunguruka butunguranye buragaruka.
Alexander khajetoorians, umwarimu wa scanning probe microscope muri kaminuza ya Radboud mu Buholandi yagize ati: "Ubu buryo bwo 'gukonjesha' ntibusanzwe mu bikoresho bya magneti."
Ubushyuhe bwo hejuru bwongera ingufu mubikomeye, amazi, cyangwa gaze.Kimwe nacyo kijyanye na magnesi: mubushyuhe bwo hejuru, kuzunguruka mubisanzwe bitangira kunyeganyega.
Khajetoorians yagize ati: "imyitwarire ya rukuruzi ya neodymium twabonye mu buryo bunyuranye n'ibibaho 'bisanzwe."Ati: "Ibi birwanya rwose, nk'uko amazi ahinduka urubura iyo ashyushye."
Ibi bintu bivuguruzanya ntibisanzwe muri kamere - ibikoresho bike bizwiho kwitwara muburyo butari bwo.Urundi rugero ruzwi cyane ni umunyu wa Rochelle: amafaranga yishyurwa akora igishushanyo mbonera ku bushyuhe bwo hejuru, ariko bigabanywa ku bushyuhe bwo hasi.
Ibisobanuro birambuye byerekana ibirahuri bya spin ni insanganyamatsiko yigihembo cyitiriwe Nobel muri 2021 muri fiziki.Kumva uburyo ibirahuri bya spin bikora nabyo ni ngombwa kubindi bice bya siyanse.
Khajetoorians yagize ati: "niba amaherezo dushobora kwigana imyitwarire yibi bikoresho, birashobora no kumenya imyitwarire y’ibindi bikoresho byinshi."
Imyitwarire ishobora kuba ifitanye isano nigitekerezo cyo kwangirika: leta nyinshi zitandukanye zifite imbaraga zimwe, kandi sisitemu iracika intege.Ubushyuhe bushobora guhindura iki kibazo: gusa leta yihariye irahari, yemerera sisitemu kwinjira muburyo bweruye.
Iyi myitwarire idasanzwe irashobora gukoreshwa mububiko bushya bwamakuru cyangwa kubara, nkubwonko nka computing.
