High-entropy effect at rare-earth site in DyCo2Si2

Abstract

We have investigated the impact of high-entropy conditions at the rare-earth site on the structural property and magnetic ordering temperature of the antiferromagnet DyCo2Si2. The lattice parameters are insensitive to the increased configurational entropy, but the antiferromagnetic ordering is suppressed under the high-entropy state. In the antiferromagnets, the competing magnetic interactions would disrupt the antiferromagnetic ordering.
