摘要：

Measurement of the complex, frequency-dependent, relative susceptibility of a number Of ferrofluids have been made in the frequency range 10 Hz 500 MHz. These measurements have revealed the presence of Brownian and Neel relaxation and in addition, for the first time, a resonance behaviour characterised by the real part of the susceptibility going negative above a frequency in the range 30-60 MHz.
