Refraction of bulk spin waves on a boundary of two homogeneous easy-axis antiferromagnetic media
Spin-wave refraction index is defined on the boundary of two bulk homogeneous antiferromagnetic media having different parameters of exchange coupling and anisotropy. The effect of spin-wave birefringence is revealed in such structure. The expression for reflection coefficient is obtained on the bou...

| description | Spin-wave refraction index is defined on the boundary of two bulk homogeneous antiferromagnetic media having different parameters of exchange coupling and anisotropy. The effect of spin-wave birefringence is revealed in such structure. The expression for reflection coefficient is obtained on the boundary. The dependencies of the reflection coefficient on frequency and value of the external homogeneous permanent magnetic field are obtained for both branches of spin wave spectrum. |
