Non-linear ac magnetic susceptibility terms viz. quadratic, chi2, and cubic, chi3, were measured versus temperature and frequency for a series of the sigma-phase Fe(100-x)Mo(x) (47<x<53) compounds. Clear evidence was found that the ground…

Magnetic properties of a sigma-phase Fe60V40 intermetallic compound were studied by means of ac and dc magnetic susceptibility and magnetocaloric effect measurements. The compound is a soft magnet yet it was found to behave like a…

The magnetic phase diagram in the H-T coordinates has been determined for {\sigma}-Fe68V32 from the ZFC/FC magnetization measurements. The re-entrant character of magnetism, going from paramagnetic through ferromagnetic to spin-glass (SG)…

Magnetization measurements were performed on two sigma-phase samples of Fe(100-x)V(x) (x=35.5, 34.1) vs. temperature, T, and in DC magnetic field, of various amplitudes. Using three characteristic temperatures, magnetic phase diagrams in…
