MAGNETOSTRICTION AND ANISOTROPY OF COXFE3-XO4(X-LESS-THAN-OR-EQUAL-TO-0.1) SINGLE-CRYSTALS

Using the strain gauge technique, the magnetostriction constants have been measured on single crystals of Co//xFe//3// minus //xO//4 with compositions 0. 005 less than equivalent to x less than equivalent to 0. 1 in the temperature range between 100 and 300 K and using magnetic fields up to 23 kOe. A linear relationship is found between the magnetostriction constants and the cobalt concentration. Some conclusions about anisotropic behavior of the samples can be made, based on the magnetostriction measurements.
