Grain growth kinetics and magnetic properties of a V-doped ZnO dilute magnetic oxide

Abstract Zn0.95V0.05O ceramics, elaborated from milled ZnO and V2O5 nanopowders, were sintered at 900, 1000 and 1100 °C for 1, 2, 4, 6, 10 and 14 h. The growth kinetics was studied identifying the grain growth exponent, the activation energy and the pre-exponential factor. The high V2O5 concentration allowed a rapid grain growth at 900 °C only at the very first stages (t
