Abstract

Structural, magnetic and thermal properties of ferromagnetic MnCo_1-xFe_xGe (0 ≤ x ≤ 0.12) compounds were investigated. The Curie temperature T_C and the martensitic transformation temperature T_M of MnCoGe (x = 0) were determined to be 340 K and 510 K, respectively. With increasing x from 0 to 0.08, T_M decreased and reached room temperature (290 K) for x ∼ 0.08. For x > 0.09, MnCo_1-x Fe_x Ge did not exhibit the martensitic transformation. The compound for x ∼ 0.08 showed a first-order magnetic transition with a thermal hysteresis of 20 K and was accompanied by the martensitic transformation in the vicinity of room temperature. The phase diagram of MnCo_1-x Fe_x Ge (0 ≤ x ≤ 0.12) is presented.
