Abstract

In this study, the structural, magnetic and magnetocaloric properties of the polycrystalline(La 0.9 Er 0.1 ) 0.85 K 0.15 MnO 3 manganite compound synthesized by sol-gel method have been studied. X-raydiffraction measurement at room temperature shows that the sample crystallizes in rhombohedralstructure. The temperature dependence of magnetization measurement reveals that the sample undergoesferromagnetic-paramagnetic phase transition with increasing temperature. Maximum magnetic entropy-1 -1change (∆S maxM ) of the sample has been calculated as 2.30 Jkg K for magnetic field change of 5 T fromisothermal magnetization curves.

Özet

Bu çalışmada, sol-jel yöntemi ile sentezlenen polikristal (La 0.9 Er 0.1 ) 0.85 K 0.15 MnO 3 manganit bileşiğinin yapısal, manyetik ve manyetokalorik özellikleri çalışılmıştır. Oda sıcaklığında x-ışını kırınımı ölçümü, numunenin rhombohedral yapıda kristalleştiğini göstermektedir. Sıcaklığa bağlı manyetizasyon ölçümleri, artan sıcaklıkla numunenin ferromanyetik-paramanyetik faz geçişi sergilediğini göstermektedir. Numunenin maksimum manyetik entropi değişimi (∆S mak. M ) izotermal mıknatıslanma eğrilerinden 5 T manyetik alan değişimi için 2.30 Jkg -1 K -1 olarak hesaplanmıştır.
