摘要

A new ThMn12-type ternary rare-earth intermetallic HoCu4Al8 has been fabricated. Magnetic susceptibility measurement on this material revealed a maximum at around 5.5 K. With a fit of high-temperature data to the Curie-Weiss law, we obtained an effective moment of 10.2μB which is close to the value arising from the free holmium ion. Together with a negative Weiss temperature of about 5.7 K, we conclude that HoCu4Al8 is an antiferromagnet and the antiferromagnetic interaction between holmium atoms is responsible for the observed magnetic nature. In addition, 27Al NMR measurements have been carried out in the paramagnetic state of HoCu4Al8. Results are found to be consistent with the antiferromagnetic characteristics of this compound.
