Crystallographic and magnetic descriptions of a novel erbium rich aluminide: Er10Co1+xAl3−x (x = 0.30)
Abstract
A novel erbium rich ternary intermetallic compound, Er10Co1+xAl3−x (x = 0.30) has been discovered in the Er–Co–Al ternary system. It crystallizes in a hexagonal ordered variant of the Co2Al5-type in presence of substitutions on two adjacent crystallographic positions. The magnetic behaviour is mainly dominated by an antiferromagnetic ordering observed at TN = 12.7(7) K
