Neutron diffraction studies of the magnetic structures of Tb0.76Y0.24 Single crystal under high pressure

The effects of high pressure on the magnetic structure of Tb0.76Y0.24 have been investigated by neutron diffraction using a clamp type high pressure c ell, Pressure was applied up to about 2.4 GPa and temperature, down to abou t 10 K, The magnetic structure of Tb0.76Y0.24 exhibits a helical phase both under high pressure and at ambient pressure, The helical pitch shows a loc k-in feature below about 100 K, With increasing pressure, the helical pitch is enhanced, and a lock-in feature at low temperature still remains, (C) 1 999 Elsevier Science Ltd.
