Magnetization reversal behaviour in ferromagnetic nanotubes (Fe-Pd and Co-Pt) was investigated using angular dependence measurements and magnetic force microscopy, which showed circumferential magnetization behaviour, which is stable at small applied field angels and coherent rotation stable at higher angles. The magnetization behaviour was also found to depend on the tube wall thickness, where it was shown that the curling is dominant in thin magnetic nanotubes.

On the invitation of the Editor of the book we wrote a chapter on complex metallic alloys as magnetocaloric materials.With the sophisticated thermal treatment we successfully influenced the final microstructure and achieved both goals. If the microstructure is changed in such a way that we get a fine dispersed secondary phase in the magnetocaloric matrix phase, the structural transformation, which is responsible for the high hysteresis losses, occurs at higher magnetic fields. By using low magnetic fields, this effect can be avoided.

I was invited from the Organizing Committee of Materialia, World Summit to present a study on Rare-Earth as the basic raw material for high energy permanent magnets. Bisedes the invited talk I also contributed to the round table discussion on scarse elements and the eventual posibilities for their replacement.
