Observation of the propagation of spin waves in antiferromagnets
Kotyuzhanskii B.Y., Prozorova L.A.
Pairs of electron and nucleaT spin waves were excited on the end face of single-crystal antiferromagnetic CsMnF3, Propagation of electron spin waves along the sample, over a length ъ 3 mm, was observed. The lifetime of the propagating spin waves is estimated at τ0 ^ 2 psec.
