Hello, I was wondering if anyone could recommend some really good sources which discuss Paramagnetism and Superparamagnetism in a fairly rigorous manner. I have been using Kittel, 7th Edition of Intro to Solid State Physics, as a reference source. I was hoping to find another reliable textbook, thesis, dissertation, or peer-reviewed article that dealt specifically with paramagnetism and superparamagnetism both mathematically and physically. I am currently writing the introduction section to my thesis in condensed matter physics and need to solidify my understanding of paramagnetism, superparamagnetism, domain formation, and size effects before I move forward. (I am working with nanoscaled iron and iron oxide systems embedded in nonmagnetic matrices.) Thank you so much for any assistance you can provide.
