Abstract: Recently, there has been a new surge of interest in Heusler alloys because of possible use of these alloys as materials for spin electronic devices. Heusler alloys also offer excellent systems for studying magnetic interactions. These alloys can be held at various degrees of order and also allow systematic substitution of one or more of the constituents. The magnetic and transport properties of these alloys can, therefore, be modified through such methods. Hyperfine interactions studies in a disordered Heusler system Fe2CrAl using Mössbauer spectroscopy, have been presented. The disorder present in the system is reflected in the X-ray diffraction and Mössbauer spectra. The system behaves like a normal ferromagnet even in the presence of disorders.
