Description

Magnetic moment and specific heat of La0.9Ca0.1MnO3 after heat treatment in oxygen and argon were studied. It is found that the sample after oxygen treatment has higher magnetic moment and specific heat than that after argon treatment. The difference of specific heat between the samples after oxygen treatment and after argon treatment has linear relationship with T3/2. The heat treatment in oxygen and argon would induce the change of oxygen density which effect the magnetic moment and specific...[Show more]
