Mössbauer studies of Fe0.7-xSi0.3Mnx Alloys

Research output: Contribution to journalArticle

Abstract

In this work we present Fe57 Mössbauer study for the alloy system Fe0.7-xSi0.3Mnx, where 0 ≤ x ≤ 0.3. Mössbauer spectroscopic results show that all the samples studied are magnetically ordered at 77 K, and at room temperature, except for x = 0.3 at 300 K where it shows paramagnetic behavior. The average magnetic hyperfine field is found to decrease with increasing the manganese concentration at 77 K and 300 K. The average magnetic hyperfine field is found to increase with decreasing the temperature from 300 K to 77 K for all samples under investigation. The average isomer shift is found to decrease with increasing the manganese concentration.
