Mössbauer study of hyperfine field distribution in Co2TiSn
Abstract
The Co2TiSn Heusler-type alloy (crystal structure L21, ferromagnetic with TC=364(4)K) was investigated by means of magnetometric and 119-Sn Mössbauer techniques in the temperature range from 4.2K to 370K. The study was supplemented by similar examination of off-stoichiometric samples: Co2±1Ti1∓1Sn. The temperature evolution of the shape of hyperfine field distribution leads to the conclusion that the process of demagnetization takes place in a non-uniform fashion within the sample volume. It is further claimed that local, short-range interactions are dominant both in magnetic and hyperfine couplings in this Heusler-type Co-based alloy.
