摘要
The complex susceptibility of magnetic liquids is investigated in a wide frequency range (10 Hz-2 GHz) with a microwave-type technique. Three loss mechanisms can be identified: Brownian relaxation, Neel relaxation and natural spin resonance. The effect of the temperature on Neel relaxation and natural spin resonance is confirmed theoretically.
