Neutron diffraction and Mössbauer measurements for magnetism of BCC Cr-Fe-Mn alloys
Journal of Magnetism and Magnetic Materials(1998)
摘要
The successive magnetic transition of BCC Cr65.0Fe20.0Mn15.0 alloy has been studied by neutron diffraction and Mössbauer effect measurements. An antiferromagnetic 1 0 0 scattering and the hyperfine field at Fe sites were confirmed to appear just below TN by neutron diffraction and Mössbauer effect, respectively. The hyperfine field distribution estimated from the Mössbauer spectra has two peaks below 150 K. The amount of Fe atoms for the peak of the high-field part increases with decreasing temperature at around Tc. The position of the high-field peak shifts remarkably to higher field below Tg with almost keeping the fractional area for this peak.
