علماء الفيزياء بجامعة موسكو الحكومية يفسرون السلوك المغناطيسي غير المألوف لبلورة حديدية

كشف علماء من جامعة موسكو الحكومية عن الآلية الكامنة وراء السلوك المغناطيسي غير المألوف لبلورة “Fe₂SeO”، وهي بلورة مضادة للبيروفسكايت أساسها الحديد. تُظهر دراستهم أن المادة لا تستقر على حالة مغناطيسية واحدة فورًا، بل تتغير على مرحلتين مع انخفاض درجة الحرارة، وذلك بسبب الطريقة الخاصة التي تترتب بها أيونات الحديد في شبكتها البلورية.
