| Abstract: | The dispersion relations of magnetostatic surface wave, which has higher and lower frequency branches, on an antiferromagnetic plane surface are studied in the case that the bias magnetic field is oriented arbitrary within the surface of the antiferromagnet. It is show that the direction of the energy flow of two branches of the wave are sensitive to the direction and amplitude of the bias magnetic field, and can be controlled to deflect up to 90 degrees. |
