The effect of Zr addition on nanostructure and magnetic properties in nanocrystalline SmZrCo has been investigated. (Sm, Zr)Co with the CaCu structure was synthesized by melt spinning. The lattice parameters a and b decrease with x, whereas c increases. Thus, the unit cell volume of (Sm, Zr)Co shrinks because the smaller Zr atoms occupy...
The authors studied the influence of microstructure and grain size, as well as Curie temperature, on the low-temperature aged Sm(Co0.45Cu0.4Fe0.15)5 alloy in relation to enhanced coercivity. Melt-spinning has been employed in order to achieved a wide range of grain sizes from micro- to nanometer level. XRD and TEM analysis were used to study the structure of as-spun ribbons and SQUID magnetometer...
