What is the microscopic origin of d(0) ferromagnetism and its type of exchange interaction in case of metal oxide(ZnO, TiO2) nanostructured materials?

There are many reports on defect related ferromagnetism in Oxide materials. Also its saturation moment is quite low and it varies a lot depending on the growth process. So is it possible to use it...

What is Magnetic Polaron, it's role in ferromagnetic interactions and in what kind of magnetic materials?

As far my understanding tells, a BMP is a particular type of molecule-complex in an occupied donor or an acceptor. Bound electrons (holes) trapped by the defect states can couple with the...

How can we measure and show the presence of spin polarized carriers in the magnetic semiconducting materials?

In general if we can produce a good quality magnetic semiconducting material (Like Nanorods, Nanoparticles or a Thin film) by doping TM(Mn, Co, Ni) in a semiconducting host(ZnO, TiO2, GaN) system...
