ABSTRACT
The temperature dependence of the magnetostrictive properties Cu0.6Co0.4Fe2O4 and CoFe2O4 samples was investigated. At 300 K, strain magnitude sample increased with increasing magnetic fields reached a maximum value at approximately 0.8 T. Upon further fields, gradually decreased almost saturated 7 Compared to sample, exhibited more pronounced increase in as decreased. In addition, T clear 100 unlike that obtained sample. showed 911 ppm K by changing direction field, which is significantly larger than Thus, range 10–300 K. Therefore, partial substitution Cu for Co very effective enhancing across wide range, including room temperature.
