FIG. 1.

(a) Experimental configuration with longitudinal geometry, (b) schematic diagram of the coherent excitation process of uniform magnetization precession, (c) transient Kerr signal, and (d) Fourier transforms of (c) after picosecond excitation of a thick epitaxial Fe film with magnetic field applied along [110], [100], and [1-10] directions.

FIG. 2.

(a) Precession amplitude and (b) frequency as a function of sample orientation at magnetic field . The dashed line is a guide for the eyes.

Image of FIG. 3.
FIG. 3.

(a) Precession frequency versus applied magnetic field along [100] and [1-10] axes. The solid line is a fit by Eq. (1). (b) Gilbert damping parameter vs applied magnetic field along [100] and [1-10] directions.
