علماء روس يكتشفون “مفتاحا حراريا” داخل الموصلات الفائقة من نوع “شبه البلورات”

By سبوتنيك عربي · 1 hour ago · 1 min read سبوتنيك عربي ↗

اكتشف باحثون من الجامعة الوطنية للبحوث النووية، ومعهد موسكو للفيزياء والتكنولوجيا، وجامعة HSE، أن مجرد تغيير درجة الحرارة يمكن أن يعيد تنظيم الدوامات المغناطيسية داخل شبه بلورة فائقة التوصيل، ففي درجات الحرارة المنخفضة جداً، تتبع الدوامات البنية غير المألوفة للمادة، ولكن مع ارتفاع درجة حرارة المادة، تعيد الدوامات تنظيم نفسها في نمط مثلثي منتظم.
