The anisotropy of R(R=Pr, Nd)-Fe-B-Cu magnets prepared by hot-pressing was investigated. For that purpose, anisotropy factor(f_a)was introduced. Also, the effects of thickness reduction ratio, working temperatures and heat treatment on the magnetic properties for R-Fe-B-Cu magnets were studied. Induced anisotropy parallel to press direction by hot-pressing was confimed through the variation of magnetic properties and domain patterns of R-Fe-B-Cu magnets. Anisotropy factors were increased according to the increment of thickness reduction and working temperature. But heat treatment of the R-Fe-B-Cu magnets had no relation with anisotropy factors. Irregularities and swelling of the specimen during the pressing were alluded.
