Spin fluctuations in the quasi-two-dimensional Heisenberg ferromagnet GdI2 studied by electron spin resonance
Abstract
The spin dynamics of GdI2 have been investigated by electron spin resonance (ESR) spectroscopy. The temperature dependences of the resonance field and ESR intensity are well described by the model for the spin susceptibility proposed by Eremin et al. [Phys. Rev. B 64, 064425 (2001)]. The temperature dependence of the resonance linewidth shows a maximum similar to the electrical resistance and is discussed in terms of scattering processes between conduction electrons and localized spins.
