摘要: Results of neutron diffraction measurements on TbNiSn in magnetic fields up to 6T are reported. This material shows successive phase transitions at T1 = 7.6 K, T2 6.0 T3 2.0 K and TN 18.5 zero field, a giant magnetoresistance effect (GMR) near four metamagnetic low temperatures. Propagation vectors main signatures the phases appearing elevated applied along b axis temperatures determined. We find large hysteresis several boundaries. In some cases co-existence structures is detected.
