摘要：

Using nonrelativistic spin quantum fluid theory, parallel propagating electromagnetic waves in electron-positron plasma immersed in a uniform external magnetic field have been investigated. With the inclusion of the spin effect of the plasma species, Faraday rotation appears, which is absent in usual electron-positron plasmas without spin effects. New resonance frequencies and extra cutoffs are observed for both right-hand and left-hand circularly polarized waves.
