摘要

We have measured transport and magnetic properties of polycrystalline La0.5Ca0.5Mn0.95Fe0.05O3 a phase separated manganite with ferromagnetic ground state. Cooling rate dependences and time relaxation were found; the coexistence of ferromagnetic and charge ordered regions determines a dynamics which influences physical properties. We show that a dynamical contribution to the resistivity can account for the observed cooling rate dependence and ageing effects on this phase separated manganite. (C) 2002 Elsevier Science B.V.
