- Abstract
The magnetic properties and crystal structure of the Pr0.5Sr0.5Co0.5Fe0.5O3 compound are studied by neutron and x-ray diffractions using synchrotron radiation. These measurements show that this compound is a dielectric spin glass with a magnetic moment freezing temperature of about 70 K. As temperature decreases in the range 30–95 K, a structure phase transition of the first order occurs with an increase in the symmetry from orthorhombic (space group Imma) to tetragonal (space group I4/ mcm). It is assumed that the transition is caused by a change in the 4 f electron configuration of the Pr3+ ions.
