What is the possible reason for the observation of increasing Corecive energy with increasing temperature in magnetization versus field plot

Hello all, Usually, the coercive force necessary to drive the magnetization back to zero in hard and soft magnets decreases with increasing temperature. This means that if we carry out a...

How does electronegativity of coordinated ligands affect the XPS spectra of a complex?

We can use XPS to investigate/determine chemical identity of metal ions in complexes. For example, we expect the binding energy of Fe3+ to be higher than a neutral Fe atom and Fe2+ because of the...
