Abstract
We present here the results of a detailed investigation on magnetic and transport properties of La{sub 0.5}Sr{sub 0.5}Co{sub 1-x}Fe{sub x}O{sub 3} (x=0, 0.1) compounds. It is shown that the Curie temperature (T{sub C}) decreases slightly and the resistivity increases, even with a very small extent of Fe substitution. There was an evident coexistence of cluster glass (CG) and spin glass (SG) behaviors for x=0 composition. The Fe substitution induced additional antiferromagnetic Fe-O-Fe interactions that suppress strongly the ferromagnetism and conductivity, thus causing a phase separation for x=0.1 composition. We also figure out the nature of CG and SG behaviors and the influence of Fe doping on magnetic and transport properties of such a cobaltite system relying on electron paramagnetic resonance spectra.
