Vatsvagiri vakacherekedza hunhu hutsva hutsva kana magineti yakadziirwa.Kana tembiricha ichikwira, iyo magineti inotenderera muchinhu ichi "inotonhora" kuita static mode, inowanzoitika kana tembiricha yadonha.Vatsvagiri vakaburitsa zvavakawana mujenari Nature Physics.
Vatsvakurudzi vakawana chiitiko ichi mune neodymium zvinhu.Makore mashoma apfuura, vakatsanangura chinhu ichi se "self induced spin girazi".Spin girazi rinowanzoita simbi alloy, semuenzaniso, maatomu esimbi anosanganiswa zvisina tsarukano mugridi yemaatomu emhangura.Atomu rimwe nerimwe resimbi rakafanana negineti duku, kana kuti kuruka.Aya ma spins akaiswa zvisina tsarukano anonongedza munzira dzakasiyana siyana.
Kusiyana nemagirazi echinyakare anotenderera, ayo akasanganiswa zvisina tsarukano nemagetsi magineti, neodymium chinhu.Mukushaikwa kwechimwe chinhu, inoratidza hunhu hwe vitrification muchimiro chekristaro.Kutenderera kunoumba patani yekutenderera semhepo inotenderera, iyo inongoitika uye inogara ichichinja.
Muchidzidzo chitsva ichi, vaongorori vakaona kuti pavakadziyisa neodymium kubva -268 ° C kusvika -265 ° C, inotenderera "yakaomeswa" kuita pateni yakasimba, ichigadzira magineti patembiricha yepamusoro.Sezvo zvinhu zvinotonhora, iyo inotenderera isina kutenderera pateni inodzoka.
“Iyi nzira ‘yokuomesa nechando’ kazhinji haiwaniki muzvinhu zvine magineti,” akadaro Alexander khajetoorians, purofesa wekuongorora maikorosikopu paRadboud University kuNetherlands.
Tembiricha yepamusoro inowedzera simba muzvakaoma, zvinwiwa, kana magasi.Izvi zvinoshandawo kune magineti: pakupisa kwepamusoro, kutenderera kunowanzotanga kuzununguka.
Khajetoorians vakati, "magineti maitiro eodymium atakaona anopesana nezvinoitika" kazhinji.""Izvi hazvina musoro, sezvinoita mvura inoshanduka kuita ice kana yapiswa."
Ichi chinopesana chiitiko hachina kujairika mune zvakasikwa - zvishoma zvinhu zvinozivikanwa kuzvibata nenzira isiriyo.Mumwe muenzaniso unozivikanwa ndeyeRochelle munyu: macheji ayo anoumba pateni yakarairwa patembiricha yakakwira, asi inogoverwa zvisina tsarukano pakudziya kwakadzika.
Iyo yakaoma theoretical tsananguro ye spin girazi ndiro dingindira re2021 Nobel Prize mufizikisi.Kunzwisisa kuti magirazi aya anotenderera anoshanda sei kwakakosha kune dzimwe nzvimbo dzesainzi.
Khajetoorians vakati, "kana tikakwanisa kutevedzera maitiro ezvishandiso izvi, zvinogona zvakare kukanganisa maitiro ehuwandu hwezvimwe zvinhu."
Inogona eccentric maitiro ane hukama neiyo pfungwa yekuderera: nyika zhinji dzakasiyana dzine simba rakafanana, uye sisitimu inogumbuka.Tembiricha inogona kushandura mamiriro aya: chete mamiriro chaiwo aripo, achibvumira sisitimu kuti ipinde pachena modhi.
Hunhu uhwu husinganzwisisike hunogona kushandiswa mukuchengetedza ruzivo rutsva kana pfungwa dzekombuta, senge uropi senge komputa.
