摘要：

We present a comprehensive analysis of the Dzyaloshinsky-Moriya interaction and crystal-field parameters using the angular dependence of the paramagnetic-resonance shift and linewidth in single crystals of La0.95Sr0.05MnO3 within the orthorhombic Jahn-Teller distorted phase. The Dzyaloshinsky-Moriya interaction (similar to1 K) results from the tilting of the MnO6 octahedra against each other. The crystal-field parameters D and E are found to be of comparable magnitude (similar to1 K) with Dapproximate to-E. This indicates a strong mixing of the \3z(2)-r(2)] and \x(2) -y(2)] states for the real orbital order.
