In this paper we present the Hall effect data of Fe 80-x Ni x Cr 20(14≤x≤30) alloys in four different magnetic phases within the fcc γ-phase. In the spin-glass (SG) phase (x=19) the nonlinear behaviour of the Hall resistivity (ρ H ) with field arises from the spin-orbit scattering. The temperature variation of ρ H shows broad peaks around T g for lower fields (<0.1 T) but they disappear at higher fields (1 T). We separate the ordinary (OHC) and the extra-ordinary (EHC) Hall coefficients in the ferromagnetic sample (x=30) and show their temperature variation. In the reentrant spin-glass (RSG) (x=26), again ρ H shows a nonlinear variation with field. The temperature variation of ρ H shows anomaly near both T g and T c . In the antiferromagnetic phase (AF) (x=14), ρ H increases more or less linearly with field and its temperature variation shows broad peaks around T N for lower fields.

Glass Behavior

Multimetallic Prussian blue compound Ni0.25Mn1.25[Fe(CN)6]·6.1H2O has been prepared by coprecipitation. The temperature-dependent magnetic susceptibilities show the magnet transition for the compound at 8.5 K. According to DC variable-temperature magnetic susceptibility paramagnetic Curie temperatureθis −9.32 K. The observed value of coercive field (Hc) and the remanent magnetization (Mr) for the compound are 0.32 KOe and 0.36 μB. According to study of zero-field-cooled (ZFC) and field-cooled (FC) magnetization curves and AC magnetization curves, there exists a spin-glass behaviour in the compound, which exhibits freezing temperatureTg=7.76 K, below magnetic transitionTC=8.5 K; that glass behavior is termed “reentrant” spin glass.
