ac susceptibility and electrical resistivity inFe80xNi

Abstract: ac susceptibility and electrical resistivity studies on polycrystalline Feso "Ni"Cr2O (21» x~30) alloys, with x = 21, 23, 26, and 30, between 4.2 and 80 K, are reported. A previous dc magnetization study indicated the presence of ferro-spin-glass mixed-phase behavior in x =23 and 26 alloys while the alloys with x=21 and 30 were found to be spin-glass and ferromagnetic, respectively. The present ac susceptibility results support the above picture. In the electrical resistivity study, a low-temperature minimum i… Show more

“…The complete phase diagram of these alloys was established by Majumdar and Blanckenhagen through dc magnetization and neutron diffraction measurements. 1 Later on ac susceptibility 3 and magnetoresistance measurements 4 also confirmed the proposed phase diagram. Taking advantage of the diverse magnetic properties of these alloys within the same fcc γ-phase, we tried to understand the age-old problem of relaxation dynamics.…”

“…This apparent anomalous behaviour was first theoretically addressed by Riviera [47], where the low temperature upturn of resistivity was considered to be electrostatic in origin which arises from the charge difference between dopant and the host atoms. However, later works indicate the role of magnetic scattering towards the observed Kondo anomaly [48].…”
