Abstract
The temperature dependence of the magnetoelastic properties of the CoGaxFe2−xO4 system (for x = 0.0, 0.2, and 0.4) has been studied. It has been shown that increase in temperature resulted in reduced magnetostrictive hysteresis. For both CoGa0.2Fe1.8O4 and CoGa0.4Fe1.6O4, the measuredmagnetostriction amplitudes were higher at 250 K than at 150 K. It was also shown that the temperature stability of magnetostriction in CoGa0.2Fe1.8O4 is higher than that of the other compositions studiedwhich is important for sensor applications. The highest strain sensitivity was obtained for CoGa0.2Fe1.8O4 at 250 K. Results demonstrate the possibility of tailoring magnetomechanical properties of the material to suit intended applications under varying temperature conditions.
