What are the equations for isotropic and anisotropic s-wave superconducting gap function?

I have fitted the transverse-field MuSR data to obtain the muon depolarization rate (sigma) at different temperatures. Now I want to fit the temperature variation of sigma to know the nature of...

How do we calculate real and imaginary part of AC susceptibility from real moment M' and imaginary moment M'' obtained from PPMS?

In DC magnetization, susceptibility = M/H. However, in case of AC magnetization measurements we have both dc and ac magnetic fields and ac susceptibility = dM/dH. We get M' and M'' from AC...

Could you please explain what are the commensurate and incommensure phases in magnetic materials?

We have observed in the literature review that some magnetic transitions are because of the commensurate and incommensurate phases of the Mn-ions (in multiferroics RMn2O5).

Could you please explain what is the double exchange mechanism in multiferroics (RMn2O5) ?

RMn2O5 (R = Rare-earth metal like Eu,Tb,Ho etc.) have Mn3+ and Mn4+ ions in the lattice. Ferromagnetism in such materials is attributed to the double exchange mechanism between Mn3+ and Mn4+.
