The relationship between the crystalline texture and the magnetic anisotropy in the Co-12Fe-3Nb alloy cold-rolled by 96% reduction in area was investigated through the measurements of X-ray pole figures, hysteresis-loops, and magnetic torque curves. The results obtained are summarised as follows:(1) The magnetic anisotropy of this alloy is due to the magnetic crystal anisotropy (K1) and the induced magnetic anisotropy (Ku). The shape of hysteresis-loop depends on which anisotropy is prevailing; perminvar type for Ku>K1, constricted curve for Ku1, and rectangular curve for Ku
