Nanophase dispersions of SmCo[sub 5] in either an Al or Co matrix have been synthesized by using pulsed laser deposition to deposit the SmCo aggregated grains while simultaneously sputtering either Al or Co. Smooth single phase type hysteresis loops were measured for both types of dispersed systems. SmCo[sub 5] plus Al dispersions were made that exhibited room temperature coercivities of 15 kOe with approx. 5 at. % Al and decreased to 5.7 kOe with 21 at. % Al. The SmCo[sub 5] plus Al dispersions were only marginally affected by heating in air for 30 min to 300 °C. It was possible to make SmCo[sub 5] plus Co films with loop squareness of approx. 0.83 and with room temperature coercivity approx. 10 kOe by using a Co matrix. © 2000 American Institute of Physics.
