Sv. Grigoriev et al., OBSERVATION OF 2 LENGTH SCALES OF MAGNETIC CORRELATIONS IN FENI ALLOYABOVE T-C, Physica. B, Condensed matter, 234, 1997, pp. 586-587
The magnetic phase transition in iron-nickel FCC alloy F75Ni25 doped b
y carbon was investigated. The coexistence of two different spatial sc
ales of magnetic inhomogeneities above T-C was found using neutron dep
olarization and small-angle scattering measurements.
