Study of (La1-xCax)MnO3. I. Magnetic Structure of LaMnO3

Gen Matsumoto1970-09-01Journal of the Physical Society of Japan

Magnetic properties of the perovskite-type oxide LaMnO 3 were studied in detail, experimentally and theoretically. The properly stoichiometric LaMnO 3 had a weak ferromagnetic moment in addition to the antiferromagnetic character with a Néel temperature of 141°K. It was found to be a parasitic weak ferromagnet. These…

On the Structure of Stress-Strain Relations for Time-Dependent Plastic Deformation in Metals

J. R. Rice1970-09-01Journal of Applied Mechanics

The paper is concerned with the structure of multiaxial stress-strain relations in time-dependent metal plasticity, as for transient creep and rate sensitive yielding. First, a general kinematical relation is developed between the macroscopic inelastic strain tensor and microstructural slip displacements, as modeled e…
