Research Interests

Luc Berger is well known for his theoretical studies on metallic ferromagnets such as iron, nickel, cobalt and their alloys and glasses. His research investigates the interaction of conduction electrons with spin waves, domain walls, film interfaces and other disturbances of the magnetic spin system through the s-d exchange energy and through hydromagnetic forces. The conduction electrons also undergo anisotropic scattering by magnetized chemical impurities through the spin-orbit energy.
