Temperature dependence of several resonance lines of magnetite was investigated from 4.2 K to 20 K. The frequency has no anomalous change between 4.2 K and 20 K within the accuracy of ∼0.05%. The intensities of the spin-echo signals and the widths of the resonance lines also have no abrupt change. Effects of annealing were also investigated. The resonance lines become narrower and the relaxation times become longer by annealing but the values of the resonance frequencies are unchanged.
