Query: Magnetism of a sigma-phase Fe60V40 alloy: magnetic susceptibilities and
  magnetocaloric effect studies   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
re-entrant spin-glass system. The magnetic ordering temperature was found to be
T_C ca.170 K, while the spin-freezing temperature was ca.164 K. Its relative
shift per decade of ac frequency was 0.002, a value smaller than that typical
of canonical spin-glasses. Magnetic entropy change, DeltaS, in the vicinity of
T_C was determined for magnetic field, H, ranging between 5 and 50 kOe.
Analysis of DeltaS in terms of the power law yielded the critical exponent, n,
vs. temperature with the minimum value of 0.75 at T_C, while from the analysis
of a relative shift of the maximum value of DeltaS with the field a critical
exponent Delta=1.7 was obtained. Based on scaling laws relationships values of
other two exponents viz. betha=0.6 and gamma=1 were determined.
