What is the significance of reverse susceptibility, 1/χ?

Is there a meaning of 1/χ vs temperature graph for a superconductor? Susceptibility itself is amount of magnetization to the corresponding field. If it is excluded by the sample I mean for a...

Is there a specific setting for XRD measurement on thin film?

I wonder if output power of an X-Ray diffractometer can be adjusted. For Raman measurement it is possible. What about XRD? Does it change the penetration dept (if any) in a thin film?

How can I calculate the critical current density, J, for a superconductor by using a magnetization data?

I know it is superconductive because it has a Meissner Effect. It is possible to estimate critical fields and determine J in the order of 108 A/cm2 ? Does the attached article help me?
