Magnetic behaviour of the intermetallic compound Ce(Fe0.8Al0.2)2

Abstract
The magnetic properties of the intermetallic compound Ce(Fe0.8Al0.2)2 are studied by means of magnetisation measurements as functions of temperature and field. The low-temperature magnetisation versus temperature curve shows a peak at 12.5K with remanent effects characteristic of spin-glass behaviour. At higher temperatures a second peak was observed at 165K. The nature of this second peak is qualitatively discussed.
