摘要：
The 'composite oscillator' method has been used to study the dependence of the internal friction of nickel and nickel-zinc ferrites on temperature. It is observed that the internal friction increases with increase of temperature and shows a peak at a temperature below the Curie temperature. The occurrence of the internal friction peaks has been explained in terms of the magnetic anisotropy energy and the domain wall motion.
