Sv. Grigoriev et al., ON THE PROBLEM OF 2 MAGNETIC CORRELATION LENGTHS IN AN INVAR FENI ALLOY ABOVE T-C, Physica. B, Condensed matter, 241, 1997, pp. 582-584
The magnetic phase transition in the iron-nickel FCC alloy Fe70Ni30 is
investigated using a three dimensional analysis of the neutron beam p
olarization. Thermal hysteresis of the magnetic system parameters was
found in the critical regime above T-C. A strong effect of the magneti
c field on the value of depolarization as well as the width of the hys
teresis loop is demonstrated. (C) 1998 Elsevier Science B.V. All right
