Description

We studied the effects of deoxygenation on the magnetic and electrical properties of La0.70Ca0.30Mn0.92Cr0.08Oz. M(T) has small variation with a few oxygen vacancies, but changes greatly with more vacancies. ρ(T) shows single peak, double bumps, one bump, and insulator with z decreasing, respectively. We explain them using phase separation model
