How to make mass and volume corrections to obtain magnetic contribution to the heat capacity?

I have a magnetic pyrochlore material Nd2Hf2O7 with lattice and magnetic contribution to the heat capacity. I want to subtract the heat capacity of a non-magnetic pyrochlore Lu2Hf2O7 from the...

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...

Does the canting of spins produce additional magnetic peaks in the neutron spectra?

We have observed a weak transition in the dc susceptibility of Nd2Ru2O7 at 21 K. However, this transition is absent in the heat capacity data, indicating the absence of any structural or phase...

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...

While making contacts for the magnetic tunnel junction (MTJ) device, the lift-off of SiO2 does not occur completely

We have fabricated the MTJ device. To characterize the device we are trying to make top and bottom contacts. After Ar-ion etching process, we deposited SiO2. But after this step the lift-off of...

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+.
