heal.abstractLa2/3Ca1/3MnO3 doped with Fe were studied by Mossbauer spectroscopy and neutron powder diffraction. The Mossbauer spectra (MS) reveal that Fe substitutes for Mn as Fe3+ (S= 5/2) and is antiferromagnetically coupled to the Mn host lattice. The magnetic behavior, from the neutron diffraction data, is that of atypical 3D Heisenberg ferromagnet. The temperature evolution of the MS differs from that of the neutron data, especially above 40 K. The data can be interpreted using a model based on an antiferromagnetic impurity in a ferromagnetic host. In such a system, the ground state is inhomogeneous resulting in spin states with reduced spin and the spin excitations are localized in the immediate neighborhood of the impurity atoms. Finally, at T approximate to 0.9T(c) the MS indicate the onset of charge localization. [S0163-1829(99)09101-8].en
