Abstract: | The magnetostriction constants λ100 and λ111 of Ni-Zn ferrite Ni1?xZnxFe2O4 single crystals with x equal to 0, 0.07, 0.17, 0.40 and 0.67 were measured by a three terminal capacitance method from liquid N2 to room temperatures.The constants λ100 and λ111 of Ni ferrite at liquid N2 temperature were ?43.0 × 10?6 and ?20.1×10?6 respectively.The magnitude of the constant λ100 increased with the increase of Zn concentration and took a maximum at x of about 0.33, while the magnitude of the constant λ111 decreased almost linearly with the increase of Zn concentration and then became zero at x about 0.75. |
