Magnetic ordering in Gd5Ir2Bi and Gd5Ir2Sb

AIP Advances, 2016
155Gd Mössbauer spectroscopy and neutron powder diffraction have been used to study magnetic ordering in Gd5Ir2Bi and Gd5Ir2Sb. Despite the hyperfine fields (Bhf) at the two Gd sites differing by more than a factor of two for both compounds, the moments ...
