摘要： 该文研究了在最一般情况下反铁磁膜线性静磁表面波的色散关系及上下支静磁表面波存在区间,考察了静磁表面波的色散随外偏置场H₀大小和方向变化的情况,研究揭示了反铁磁膜上下支静磁表面波能流偏转受H₀大小和方向控制在0~90°范围内可调的特性

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.
