Sa. Klimko et al., OBSERVATION OF THE MAGNETIC TEMPERATURE HYSTERESIS IN INVAR FENI ALLOY ABOVE T-C, Physica. B, Condensed matter, 234, 1997, pp. 588-589
The magnetic phase transition in iron-nickel FCC alloy Fe70Ni30-doped
by carbon (0.7 at%) was investigated by means of neutron polarization
and small-angle scattering measurements. The temperature hysteresis of
magnitude of both polarization of transmitted neutron beam and intens
ity of SANS above T-C has been found.
