Magnetic properties and microstructure were investigated in Sm17.24Co66.20Cu8.28Fe8.28 ribbons melt-spun at different wheel speeds of 5; 15; 30; 40 and 50 m/s. X-ray diffraction studies revealed that the ribbons melt-spun at lower wheel speed (7; Sm2Co7 and SmCo5; while higher wheel speed ribbons exhibited single phase SmCo5. The coercivity was found to increase with increase of the wheel speed. A high coercivity of ∼33 kOe was obtained in ribbon prepared at 50 m/s. © 2007 Elsevier B.V. All rights reserved;
