We studied electric and magnetic properties of polycrystalline La0.325Pr0.300Ca0.375MnO3, a manganese oxide-based compound exhibiting intrinsic multiphase coexistence of submicrometric ferromagnetic, charge-ordered and charge-disordered regions. Time relaxation in both resistivity and magnetization were observed in a broad temperature range, signaling that coexisting phases are out of equilibrium. Different regimes of instability are presented and discussed. (C) 2004 Elsevier B.V. All rights reserved.
