✦ Synopsis

Spin waves in the transition-metal ferromagnet cobalt have been measured to 300meV. The dispersion relations in the basal plane and along the c-axis are presented, and are compared with recent theoretical predictions. Good agreement of the acoustic modes is found. The intensities of the spin waves in the basal plane show no dramatic decrease in intensity at high energies, in contrast to iron and nickel.
