From the SWLing.com blog. I doubt that this would be easy reading....it's in PDF

PDF: Analysis and Design of FSL Antennas

Many thanks to SWLing Post contributor, Zoltan Azary, who has written an extensive theoretical analysis of ferrite sleeve loop antennas. This article has a very academic flavor and for those who ar…

Interesting read. To understand ferrite properties though, you might include engineering documents from Feroxcube and Amidon.

The amount of info about ferrite properties was limited in that article to keep the length down. It is 14 pages or so, as is. The larger report referenced in the article has a much more in depth discussion of the properties of ferrites, and there's a companion article about predicting the inductance of coils on solid ferrite rods too.
