Neutron scattering study of TbPtln intermetallic compound

The magnetic properties of a TbPtIn single crystal-crystal were studied as a function of temperature and magnetic field was. Neutron diffraction measurements were performed over the 4.2-300 K temperature range using three different single crystals oriented in such a way that their a-b and a-c planes, and the plane defined by the [101] and 12̄0] direction coincided with the horizontal scattering plane respectively. It was found that the magnetic moments were parallel to the [12̄0] direction in the absence of an externally applied magnetic field. The measurements at 4.2 K with a magnetic field applied along the [12̄0] direction showed metamagnetic transitions at approximately 20 kG and 40 kG.
