Abaphenyi babona indlela yokuziphatha entsha engaziwa lapho kufuthelwa khona izinto zikazibuthe. Lapho izinga lokushisa likhuphuka, i-magnetic spin kule ndaba "iqhwa" kwimodi ye-static, evame ukwenzeka lapho amazinga okushisa ehla. Abaphenyi bashicilela okutholakele kwabo ku-Journal Natural Physics.
Abaphenyi bathole le nto ngezinto zokwenziwa ze-neodymium. Eminyakeni embalwa edlule, bachaze le nto ngokuthi "ingilazi ye-spin spin". Ingilazi ye-SPIN imvamisa i-alloy yensimbi, ngokwesibonelo, ama-athomu e-iron ahlanganiswa ngokungahleliwe kwigridi yama-athomu ethusi. I-athomu ngayinye yensimbi ifana nozibuthe omncane, noma spin. Lokhu kubekwe ngezikhathi ezithile ama-spins ngamaphuzu ahlukahlukene.
Ngokungafani nezibuko zendabuko ze-spin, ezihlanganiswa ngezikhathi ezithile ngezinto ezibukwe, i-neodymium yinto ethile. Uma kungekho enye into, kukhombisa ukusebenza kwe-Vitricution ngefomu le-crystal. Ukujikeleza kwakha iphethini yokujikeleza efana ne-sorarish, engahleliwe futhi eshintsha njalo.
Kulolu cwaningo olusha, abacwaningi bathola ukuthi lapho befudumeza i-neodymium kusuka ku-268 ° C kuye ku-265 ° C, i-spin yayo "iqhwa" kwiphethini eliqinile. Njengoba impahla epholile, iphethini ezungeza ngokungahleliwe.
“This mode of 'freezing' usually does not occur in magnetic materials,” said Alexander khajetoorians, a scanning probe microscope professor at Radboud University in the Netherlands.
Amazinga okushisa aphezulu akhulisa amandla kuma-solid, uketshezi, noma amagesi. Okufanayo kusebenza kuma-magnets: emazingeni okushisa aphezulu, ukujikeleza kuvame ukuqala ukweqa.
Ama-Khajetooris athi, "Ukuziphatha kazibuthe kweNeodymium esikubonile empeleni okuphambene nalokho okwenzekayo 'okujwayelekile'." "Lokhu kuyinto enembile impela, njengamanzi aphenduka eqhweni lapho efudumele."
Le nto enobuthi ayivamile emvelweni - izinto zokwakha ezaziwayo ukuziphatha ngendlela engafanele. Esinye isibonelo esaziwayo usawoti we-rochelle wusawoti we-rochelle: amacala awo akha iphethini evulekile emazingeni okushisa aphezulu, kepha asatshalaliswa ngezikhathi ezithile emazingeni okushisa aphansi.
Incazelo eyinkimbinkimbi ye-Theoretical of Spin Glass yisihloko soMklomelo kaNobel ongu-2011 ku-physics. Ukuqonda ukuthi lezi zingilazi ze-spin zisebenza kanjani nazo kubalulekile kwezinye izindawo zesayensi.
Ama-Khajetooris athi, "Uma singagcina silingisa indlela yokuziphatha kwalezi zinto zokwakha, futhi singaphambanisa nokuziphatha kwenani elikhulu lezinto ezithile."
Ukuziphatha okungaba khona okuhlobene kuhlobene nomqondo wokuwohloka: Izizwe eziningi ezahlukahlukene zinamandla afanayo, futhi uhlelo luyakhungatheka. Ukushisa kungashintsha lesi simo: Isimo esithile kuphela esikhona, esivumela uhlelo ukuthi lifake ngokusobala imodi.
Lokhu kuziphatha okungajwayelekile kungahle kusetshenziswe kwisitoreji solwazi esisha noma imiqondo yekhompyutha, efana nengqondo efana ne-computing.
