Abstract
The Mössbauer effect measurement of ⁵⁷Fe has been performed for Fe_a-xMn_xAs system (a = 2.0, 2.1). This system has three several magnetic phases, which are Fe₂As type and Mn₂As type antiferromagnetic phases and a ferromagnetic phase. The magnetic hyperfine field depends strongly on magnetic structure.
