Two-magnon absorption in Nd2CuO4
The two-magnon absorption of the electromagnetic waves in the exchange noncollinear magnetic phase of four-sublattice antiferromagnet Nd2CuO4 has been considered. The spin-wave density of states and the frequency dependencies of the absorption coefficient have been calculated. It is shown that the i...

| Zusammenfassung: | The two-magnon absorption of the electromagnetic waves in the exchange noncollinear magnetic phase of four-sublattice antiferromagnet Nd2CuO4 has been considered. The spin-wave density of states and the frequency dependencies of the absorption coefficient have been calculated. It is shown that the intensity of the two-magnon absorption by exchange magnons in exchange-noncollinear magnets is substantially larger than in magnets collinear in the exchange approximation. |
