MAGNETIC PHASE-TRANSITIONS IN THE FE1-XMNXSN2 ALLOYS FOR 0 LESS-THAN-OR-EQUAL-TO X LESS-THAN-OR-EQUAL-TO 1.0 - A MOSSBAUER AND MAGNETIZATION STUDY

57Fe Mössbauer study of the pseudo-Binary alloys Fe1-xMnxSn2 for 0≤x≤1.0 reveal the antiferromagnetically ordered state at 79K for all the specimens of the series. The hyperfine field at Fe site decreases with increasing manganese concentration. Magnetic susceptibility measurements performed in the temperature range 80 K≤T≤300 K indicate that the Néel temperature decreases with increasing Mn concentration for the samples with x≤0.4 whereas it increases continuously for the specimens having x>0.4 of the alloy series. © 1990 J.C.
