Electron Spin Resonance Study of Polycrystalline La0.4Bi0.1Ca0.5MnO3

Autor: W. Boujelben, R. Thaljaoui, A. Krichene

Publikováno v: Journal of Superconductivity and Novel Magnetism. 28:1881-1885

We have inspected the magnetic properties of polycrystalline La0.4Bi0.1Ca0.5MnO3 using electron spin resonance (ESR) in the temperature range 150–280 K. The temperature dependence of magnetization indicates that the Curie temperature is T C= 225 K.
