摘要：
We report time differential perturbed angular distribution measurement of Fe-54 on polycrystalline SrFe2As2. The local susceptibility measured shows a Curie-Weiss like temperature dependence in the paramagnetic region. Below T-N = 202 K, the hyperfine field shows two components, the low field component showing a power law dependence of 0.25 on temperature.
