How to use constraint in Rietveld refinement?

I am working on spinel ferrites (AB2O4). Since cations in spinels can occupy both tetrahedral and octhedral sites, I need to find out the amount of cations occupying the tetrahedral and octahedral...

How to use more than one instrument driver in a single labVIEW task to measure input vs output curve?

I am trying to measure magnetostrictive strain as a function of applied DC magnetic field. For this, I am using NI9237 module sitting on a chassis for strain measurement, and a lakeshore 425...

How is the magnetoelectric current measured?

Measurement of magnetoelectric current (density) seems to be very popular to investigate the magneto-electric response of multiferroics. It'll be grateful to know how it is measured and about the...

How to determine the r1, r2 values of dual mode MRI contrast agent when T1, T2 relaxations are for two different compounds (sample is composite)?

I have developed a nanocomposite of two different systems. Individually, one of the systems is a good T1 contrast agent and the other is a good T2 contrast agent. Interestingly, both of them...

Can R-R interaction in orthoferrites become predominant with high rare earth concentration and what is the effect of high temperature?

Many articles states about three interactions (Fe-Fe, Fe-R, and R-R) in orthoferrites either at or below Neel Temperature. Not many evidence were found regarding the predominant interactions at...

How the value of surface layer (skin) capacitance of a crystal differs from that of grain boundaries and grains?

It is reported that several important pervoskites like SrTiO3, BaTiO3 have surface layers that are structurally different from the interior of crystal. Further, it can show transition similar to...
