摘要：

Electron spin relaxation times T-1 and T-2 of La@C-82 in CS2 were measured by Fourier transform electron paramagnetic resonance at temperatures from 283 to 173 K. The obtained relaxation times show a clear m(I), dependence of La and its features change with temperature. Analysis of the temperature dependence of the electron spin relaxation times indicates that there is a thermal equilibrium between two configurations having different magnitudes for the anisotropy parameters in La@C-82.
