Magnetic and Resonance Properties of the Y.sub.0.5Sr.sub.0.5Cr.sub.0.5Mn.sub.0.5O.sub.3 Polycrystal

The magnetostatic and magnetic resonance properties of the Y.sub.0.5Sr.sub.0.5Cr.sub.0.5Mn.sub.0.5O.sub.3 polycrystalline system have been experimentally investigated. The predominance of the intracrystalline ferromagnetic interaction and the antiferromagnetic character of the intercrystallite interaction have been established. The magnetic resonance spectrum in the magnetically ordered region consists of two lines. The high-field line corresponds to the interacting parts of polycrystal shells and the low-field peak is related to the disordered system of ferromagnetic particles.
