Abstract

We have measured the specific heat, electrical resistivity, and magnetic susceptibility of Ba2 MnZn2As2O2. This phase has a magnetic transition at 30 K, and zero-field-cooled and field-cooled magnetic susceptibilities separate below this transition. The specific heat has a γT term suggesting a spin-glass-like state. The electrical resistivity is semiconducting with an activation energy of 1070 K, which rapidly decreases at the rate of -106 K/GPa.
