Abstract

The magnetic and structural behaviors of a single crystal of La _0.8Ca_0.2MnO₃ were investigated in terms of magnetic and neutron diffraction measurements. The frequency-dependent ac magnetic susceptibility reveals that cluster-glassy phase evolves below the Curie temperature (T_C) in this system, suggesting the existence of short-range correlation below T_C embedded in the ferromagnetic (FM) background. A correlation of the magnetic properties in La_0.8Ca _0.2MnO₃ with the buckling of MnO₆ octahedra is discussed based on its temperature-dependent neutron and magnetization data.
