Matsa ƙananan lu'ulu'u tsakanin faranti na titanium ya sauya halinsu na maganadisu a gwaje-gwajen da Oak Ridge National Laboratory ta bayyana ranar 27 ga Oktoba. Aikin yana nazarin matsin jiki a matsayin hanyar sarrafa kayan da wata rana za su taimaka wa wani tsarin lantarki.
Masu binciken sun yi nazarin manganese telluride da iron sulfide. Auna neutron a Spallation Neutron Source na dakin gwajin ya nuna sauye-sauye a rabon yankunan maganadisu. Tawagar ta kuma lura da sauyin wani martanin lantarki da ake kira anomalous Hall effect.
Ana nazarin kayan dangane da altermagnetism. Ɗaya daga cikin yiwuwar amfaninsu shi ne spintronics, wanda yake amfani da spin na electron tare da cajinsa na lantarki. Wannan shi ne dalilin sha'awar fasaha, ba shaidar cewa gwajin ya riga ya samar da sabuwar kwamfuta ba.
Gwajin ya haɗa aikin da aka yi a waje da abin da yake faruwa a ciki: a matsa cikin tsari, sannan a duba abin da ya sauya a lu'ulu'u. Neutron diffraction yana taimaka wa masana su binciki wannan ɓoyayyen tsari, yana ba da bayanin tsarin da ke bayan sauyin lantarkin.
Dakin gwajin ya ambaci takardun bincike a Physical Review X da Advanced Materials. Rahoton bai ba da ranar fara sayar da wani samfur ba. Bai kuma kamata a ɗauke shi a matsayin shawarar matsa maganadisu na gida ko sassan na'ura don inganta aikinsu ba.
Muhimmancin binciken yana matakin fahimtar kayan aiki. Sanin yadda ake sauya yankunan maganadisu na iya taimakawa wajen tsara gwaje-gwaje da na'urori na gaba. Tambayoyi kan yanayin aiki, maimaituwar sakamako da haɗawa da sauran sassa suna jiran mataki na gaba bayan wannan nuna yiwuwar sauyi.
