摘要：
Calculations are presented for dipolar surface spin waves in antiferromagnets at low temperatures. The authors calculate bulk and surface spin wave spectra for long wavelengths in the magnetostatic mode region. The different phases in an applied field along the easy axis are discussed with special emphasis on the spin flop- and paramagnetic phase. Nonreciprocal features of the surface spin waves are discussed. Numerical applications for GdAlO//3 are given.
