Probing magnetic phase separation in manganites by nonlinear susceptibility

At low frequencies ν≤300Hz, nonlinear magnetic susceptibility of polycrystalline La0.7Pb0.3Mn0.8(Co, Ni)0.2O3 samples near the ferromagnetic (FM)–paramagnetic (PM) phase transition reinforces the earlier observation, based on linear ac susceptibility, that these systems behave as a three-dimensional...
