The structural and magnetic properties of Mn 2+delta;TiSn prepared by arc melting and annealing have been investigated. Structural studies show that the compound crystallizes in the hexagonal Ni 3Sn-type structure with a 5.70 Å and c 4.55 Å. The phase stability of Mn 2TiSn in the hexagonal structure is supported by the first-principle electronic structure calculations where the total energy per unit-cell volume in the hexagonal structure is smaller than that in the cubic structure. Field and temperature dependence of magnetization show that the sample is magnetically ordered with a Curie temperature around 400 K. The anisotropy energy calculated from the high-field data is 4.0 × 10 5 ergs/cm 3 at 300 K but increases by a factor of two (8.6 × 10 5 ergs/cm 3) as temperature decreases to 10 K. The observed magnetic properties are explained as the consequences of competing ferromagnetic and antiferromagnetic interactions between different magnetic sublattices.
