An Analytical Theory of FMR in Bulk Metals (Parallel Configuration). II. Penetration Depths

Abstract

Abstract The general formulae for the penetration depths of the three waves, which are excited in a bulk ferromagnetic metal in the ferromagnetic resonance (FMR) region, are evaluated for parallel configuration and compared with the antiresonance skin‐depth expression. The concept of the FMR “effective skin‐depth” is introduced.
