Abstract
57Fe Mossbauer studies in the system Ce(Fe1-xCox)2 for x=0.15 and 0.25 have shown the sudden loss in magnetisation in this system, well bellow the onset of long-range ferromagnetic order, arises due to the reorientation and locking of Fe moments in such a way as to produce almost zero net magnetisation. The thermal variation of the average hyperfine field, however, does not have any signature of the reorientation transition temperature.Keywords
