Description
We report time differential perturbed angular distribution measurement of 54Fe on a polycrystalline EuFe2As2 sample. The local susceptibility measured shows Curie-Weiss like temperature dependence in the paramagnetic region. The spin-lattice relaxation observed shows Korringa like relaxation and changes discontinuously at TS = T N= 190 K. Below TN, the hyperfine field shows two components. The low filed component of the hyperfine field shows a power law dependence of 0.27 on temperature. (author)
