| Popis: | We studied electric and magnetic properties of polycrystalline La 0.325 Pr 0.300 Ca 0.375 MnO 3 , 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. |
