摘要

The variation of NMR spectra and magnetization with temperature in (R_(1-x)R'_x)_2Co_(14)B (R = Y or Gd, R' = Tb, Dy or Ho 0 ≤ x ≤ 1) have been measured. These compounds undergo spin reori-entation at a temperature T_(SR) when Y and Gd are substituted by Tb, Dy and Ho, and the temperature T_(SR) increases with the fraction x. Phase diagrams of spin arrangement in these systems have been obtained. The results are discussed from the view point of competition between the crystalline electric field and the Co-R exchange interaction.
