Microstructure and magnetic properties of uncoupled Sm2Co17–Cu nanocomposites. Zhang, J. X., Bessais, L., Djéga-Mariadassou, C., Leroy, E., Percheron-Guégan, A., & Champion, Y. Applied Physics Letters, 80(11):1960–1962, March, 2002. 00000
Paper doi abstract bibtex Nanocomposite Sm 2 Co 17 – Cu particles have been fabricated by low energy comilling of mechanically alloyed Sm 2 Co 17 particles with Cunanoparticles. The x-ray diffraction analyses show that the diffraction crystallite size (DCS) of Sm 2 Co 17 decreases with increasing comilling time. Scanning and transmission electron microscopy observation demonstrates that the particle size is in the range of the DCS and the Sm 2 Co 17 particles are separated by Cu particles. The coercivity as well as the remanence ratio decreases with increasing milling time due to the grain size reduction and grain separation. The nanocomposite Sm 2 Co 17 – Cu exhibits suitable magnetic and microstructureproperties for high-density recording.
