Pressure Dependence of Disaccommodation in a Manganese Zinc Ferrite Single Crystal

Abstract
The disaccommodation in a Mn0.56Zn0.35Fe2.09O4 single crystal is studied in the temperature range from 250 to 300 K and a pressure range from 1 bar to 3.7 kbar. The results are analyzed using a model of Richter type magnetic after-effect. The values of the activation energy and the activation volume are estimated to be 0.59 eV and 1.2 cm3/mol, respectively. The results are discussed qualitatively in terms of existing theories.
