MAGNETIC BEHAVIOUR OF Co IN YCo4-xCuxB COMPOUNDS
Journal Title: Journal of Science And Arts - Year 2008, Vol 9, Issue 2
Abstract
The RCo4B compounds, where R is a rare-earth or yttrium crystallize in a hexagonal structure of CeCo4B-type. In this lattice, the R atoms are located in 1a and 1b sites, Co in 2c and 6i sites and B in 2d positions. The mean cobalt moments, MCo, were shown to be sensitive to R partner, exchange interactions respectively. The exchange interactions may be also modified by substituting, in the above compounds, cobalt by a nonmagnetic element. In this way, additional information on cobalt magnetic behaviour can be obtained. The YCo4-xCuxB compounds are ferromagnetically ordered.
