Description

One studied temperature and magnetic field dependences of magneto-thermal effect (MTE) in La0.9Ag0.1MnO3, La0.8Ag0.2MnO3, La0.8Ag0.15MnO3 manganites. One revealed temperature substantial changes of specimens at magnetic field variation by ΔH = 26 kOe. Temperatures of MTE maximums are close to the room temperature values. One revealed association between process to make specimens and magneto-thermal features

Abstract (Russian)

Исследованы температурная и магнитополевые зависимости магнитокалорическоro эффекта (МКЭ) в манганитах La0.9Ag0.1МnО3, La0.8Ag0.2МnO3, La0.8Ag0.15МnO3. Обнаружены rигaнтcкие изменения температуры образцов при изменении магнитного поля на ΔH = 26 кЭ. Температуры максимумов МКЭ находятся вблизи комнатных температур. Установлена связь между технологией получения образцов и магнитокалорическими свойствами
