Popis:	Measurements of spin waves in antiferromagnetic single domain FCT γ-Mn(10% Fe, 3% Cu) alloy at a temperature of 4.2 K and at energies up to 103meV have a given velocity, v= 290 ± 15meV A , energy gap, Eg=12+0.5meV, and damping parameters, Γ 0 =1meV, and Γ 1 =100 meV A . The intrinsic linewidths are finite and there is no evidence for any anisotropy of the spin-wave dispersion relation.
