    The roll reduction and concentration dependences of the uniaxial magnetic anisotropy induced by cold-rolling, Kur, were investigated for hexagonal Co and Co-Fe alloys. The maximum value of Kur was 3×105 erg/cm3 at 10%-20% roll reduction for Co and Co-1.5% Fe. The easy direction was perpendicular and parallel to the rolling direction for the alloys containing less than 1.2% Fe and more than 1.2% Fe at room temperature, respectively. The easy direction of Kur changed at 260 °C for Co. The texture produced by cold-rolling was detected by Schulz's method. The induced anisotropies were evaluated by using the Ku1, Ku2, and the x-ray reflected intensities. The calculated values and easy direction agreed well with the experimental results. The origin of K ur for hexagonal Co and Co-Fe alloys is clearly explained by formation of rolling texture.
