Magnetization steps in phase separated La0.5Ca0.5Mn1-yFeyO3
2004
We report a low temperature magnetic study on the phase separated polycrystalline manganites La0.5Ca0.5Mn1−yFe y O3 (0.02≤y≤0.06). Several abrupt and sizeable magnetization steps are observed in the M(H) curves of all samples at 2 K, which are associated to avalanche-like growth of the ferromagnetic phase. This work contributes to confirm that this feature is inherent to phase separated manganites, and is not restricted to particular compounds or kinds of doping.
