Mossbauer Study of Changes in Magnetic Structure of La(Fe_0.88Al_0.12-xSi_x)₁₃ Compounds

Abstract:

A first-order metamagnetic transition from antiferromagnetic to ferromagnetic state in La (Fe0.88Al0.12-xSix) compounds was investigated using Mossbauer effect. The exchange-related clusters in the ferromagnetic and antiferromagnetic state are shown to exist. The influence of Si on magnetic structure is observed.
