Notes:
Alloys of composition RCo7−xZrx (R=Pr or Er and x=0−0.8) were synthesized and characterized in the temperature range of 10–1273 K in fields up to 5 T. As with the SmCo7−xZrx system studied earlier in our laboratory, the effects of Zr doping on the stability of the TbCu7 phase and the increase in the anisotropy field HA are also observed in the systems of PrCo7−xZrx and ErCo7−xZrx. Nearly single phase TbCu7 materials were formed in as-cast alloys when x=0.1–0.2. In the case of R=Pr, HA changes from almost planar for x=0 to uniaxial with Ha∼100 kOe for x≥0.2 at room temperature (RT). In the case of R=Er, HA for the x=0.1 composition is almost two times larger than that of the Zr-free alloys, which shows strong uniaxial anisotropy at both RT and 10 K. Spin reorientation behavior (when R=Pr) and R–M antiparallel coupling (when R=Er) were also observed. © 1999 American Institute of Physics.
