摘要：
We report the first measurements of linear and non-linear ac susceptibility for (NiFe)25AU75 and the results suggest that the system is in a mixed phase i.e. ferromagnetic order coexists with spin glass-like state. We also show that the unique observation of the non-linear term chi-2, measured as the strength of the second harmonic signal (2-omega) is an important physical quantity to establish the coexistence of ferromagnetic and spin glass order because of the breaking of time reversal symmetry. This is supported by similar measurements on reentrant spin glass system Fe1.5Mn1.5Si which will also be presented.
