摘要：
Effect of preparation conditions on structural and magnetic properties of Mn and Mn-Ga spinels was investigated by Mossbauer spectroscopy and magnetization measurements. These properties were found to be significantly dependent on the quenching temperature of the samples. Evidently, quenching from elevated temperatures enhanced the magnetization of the spinels due to changes in the chemical short range order.
