摘要：

A nonlinear variation of the electron resonance frequency with resonance field characteristic of ferromagnetic resonance has been observed in a TDAE-C(60) in the radio-frequency region. The results not only definitely prove the existence of long range order below Te but also show that well annealed TDAE-C(60) behaves as an easy axis three dimensional Heisenberg ferromagnet with an exceptionally small anisotropy field H(K) = 29 G. The easy axis coincides with the crystal c direction which is the direction of closest approach of the C(60)(-) ions.
