"Experimental Methods in RF Design" has a half-dozen pages specifically on the choices of powdered iron and ferrite materials, and lots of working circuits and designs with measurements. Aka EMRFD. http://www.arrl.org/shop/Experimental-Methods-in-RF-Design
Here in the USA, iron powder and ferrite cores of many different materials, sizes, and a few shapes are available from Amidon and kitsandparts.com. Many useful ferrite cores for multi-turn transformers and chokes, are sold as "EMI beads" by Mouser and Newark and other mainline distributors. I don't know too much about easy availability in EU.
