Magnetic properiies of atomically disordered Fe 3−x V x Al alloys withx≦0.8

The magnetic properties of polycrystalline Fe_3−xV_xAl alloys with x≤0.8 having atomically disordered structure of the A2 type were investigated by magnetostatic and Mossbauer methods. It was ascertained that the magnetic moment and the Curie temperature decrease approximately linearly with increasing x. Above the Curie temperature investigated alloys do not obey the Curie-Weiss law. Marked nonlinear variations of magnetic susceptibility with magnetic field intensity indicate the existence of magnetic clusters. Mossbauer investigations also confirmed the existence of magnetic clusters with short relaxation time.
