I have a question regarind how to calculate the DOS for ferromagnetic impurities in a dielectric
We have samples with ferromagnetic rare-earth ions implanted in a dielectric material. The concentration known and is quite high but the ions are probably only interacting weakly (they are on average about 10nm apart).These ions can interact with an external field (which does not affect the dielectric).
I now need to calculate the DOS of the ions interacting with the field. However, I do not even know where to start (possibly because I haven't done anything like this in >15 years).
I believe the interactions are a bit too weak for it to be considered a spin glass. However, the usual theory for disordered glasses should apply.
Any ideas for where to start? Presumably it should be calculable since I know the concentration and the properties of the ions (and they are not interacting)
