摘要：

Powder neutron diffraction measurements have been undertaken on Pd2TiIn over the temperature range 4-300 K. Previous measurements of the bulk magnetic properties indicated a magnetic transition in the neighbourhood of 110 K. The neutron measurements reveal a structural phase transition at 92 K. The transition appeared to be of first order, and no evidence was found of any long-range magnetic order below 92 K. However, the existence of ferrimagnetic order, involving the Pd and Ti atoms, could not be ruled out. The results are discussed in terms of the stability of the magnetic moment and the presence of spin fluctuations.
