The 9.1 GHz microwave transmission against magnetic field spectrum of a high-purity tungsten single crystal coated with ferromagnetic layers is investigated. A strong transmission peak at the ferromagnetic resonance of the coating layers is attributed to longitudinal single electron spin waves (Larmor waves). The authors determined the wavelength of the spin waves from the magnetic field angle dependence of the transmission peak and by applying simple considerations the Fermi velocity around the (111) direction was derived.
