Boka revatsvakurudzi kubva kuPaul Scherrer Institute (Villigen, Switzerland) uye ETH Zurich vakaongorora uye vakasimbisa kushanda kwechiitiko chinonakidza chemagnetism pamwero weatomu. Maitiro atypical emagineti pamwero wemasumbu e nanometer akafanotaurwa makore makumi matanhatu apfuura neSoviet neAmerica nyanzvi yefizikisi Igor Ekhielevich Dzyaloshinsky. Vatsvagiri muSwitzerland vakakwanisa kugadzira zvimiro zvakadaro uye zvino vanofanotaura ramangwana rakajeka kwavari kwete chete semhinduro dzekuchengetedza, asiwo, zvisingawanzoitiki, sekutsiva kwema transistors mune nanoscale processors.
Munyika yedu, tsono yekambasi inogara ichinongedza kuchamhembe, izvo zvinoita kuti zvikwanise kuziva nzira yekumabvazuva nekumadokero. Magnets emhando dzakasiyana anokwezva, uye unipolar magineti anodzinga. Mune microcosm pachiyero chemaatomu akati wandei, pasi pemamwe mamiriro ezvinhu, magineti maitiro anoitika zvakasiyana. Muchikamu chipfupi chekudyidzana kwemaatomu ecobalt, semuenzaniso, nzvimbo dzakavakidzana dzemagineti padyo nemaatomu akananga kuchamhembe anotariswa kumadokero. Kana chinongedzo chachinja chakananga kumaodzanyemba, ipapo maatomu ari munharaunda yakatarisana anozochinja magineti ekutarisa kumabvazuva. Chakakosha ndechekuti maatomu ekudzora uye maatomu evaranda anowanikwa mundege imwechete. Kare, mhedzisiro yakafanana yaionekwa chete mumaatomu akamira (imwe pamusoro peimwe). Nzvimbo yekudzora uye inodzorwa nzvimbo mundege imwechete inovhura nzira yekugadzira komputa uye yekuchengetedza zvivakwa.
Iyo dhizaini yemagnetization yeiyo control layer inogona kuchinjwa kungave neelectromagnetic field kana nekushandisa ikozvino. Transistors inodzorwa vachishandisa misimboti yakafanana. Chete munyaya yenanomagnets ndipo panogona kugashira kurudziro yekusimudzira zvese maererano nekugadzirwa uye kuchengetedza kwekushandisa uye mukudzikisa nzvimbo yemhinduro (kuderedza chiyero chehunyanzvi hwekuita). Muchiitiko ichi, mavharuvhu achashanda akabatana magnetization zones, anodzorwa nekuchinja magnetization yenzvimbo huru.
Chiitiko chekubatanidza magnetization chakaonekwa mune yakakosha dhizaini. Kuti uite izvi, 1,6 nm gobvu dhizaini yecobalt yakakomberedzwa kumusoro uye pasi ne substrates: platinamu pasi uye aluminium oxide kumusoro (isina kuratidzwa mumufananidzo). Pasina izvi, zvakabatanidzwa kuchamhembe-kumadokero uye kumaodzanyemba-kumabvazuva magnetization hazvina kuitika. Zvakare, chiitiko chakawanikwa chinogona kutungamira mukubuda kweanogadzira antiferromagnets, ayo anogona zvakare kuvhura nzira kune hutsva tekinoroji yekurekodha data.
