Can we use Arrott plot technique for analyzing the weak ferromagnetic (canted antiferromagnetic) contribution of G-type antiferromagnetic BiFeO3 ?

Can we separate the ferromagnetic contribution from the MH loop and apply the Arrott plot to extract the saturation magnetization ? The measurement temperature for MH loop (300 K) is well below...

How does the ESR of Fe2+, Mn3+ and Fe3+ change in different crystallographic environments?

Can anyone help me to do a simulation and interpretation of ESR spectra of Fe3+ in different environment? When does the g value come about 6? What will be the effect of spin cycloidal on ESR...
