摘要
The magnetic properties of YA(4-x)M(x)B with A = cobalt (Co) or nickel (Ni) and M = Al or Cu were analyzed. Solid solutions are formed for x <= 1.5 when M = Cu and x <= 2 for M = Al. The magnetizations and Curie temperatures decrease as result of substitutions. The YCo2Al2B compound is paramagnetic. Band structure calculations were performed on the above systems. Finally, the magnetic behaviors of Co and Ni in YA(4-x)M(x)B compounds is analyzed. (c) 2007 Elsevier B. V. All rights reserved.
