摘要：
Single crystals of Ba(Fe1-xMnx)(2)As-2 (x = 0, 0.016, 0.064) have been prepared and studied by Fe-57 Mossbauer spectroscopy in the temperature range from 30 K to room temperature. The Mossbauer spectra show a change in the spectral shape with the change of Mn concentrations. It is found that both the hyperfine field and the magnetic phase transition temperature decrease with the increasing of Mn concentrations.
