摘要	Effect of Ga content on the phase constitution, magnetic phase transition temperatures (T-C), and exchange bias (EB) behaviors of Fe50Mn24+xGa26 x (x = 0, 0.5, 1, 3) as-spun ribbons have been investigated. Fe50Mn24Ga26 ribbon exhibits a magnetic phase transition of B2-type structure from FM to PM state at T-C1 = 190 K. Another magnetic phase transition of face-center-cubic structure from AFM to FM takes place at T-C2 = 240 K for Fe50Mn25Ga25 sample. The values of exchange bias field (H-E) at 10 K after field-cooling (FC) at 30 kOe from 300 K are 14, 41, 1886, 1740 Oe, respectively, as x is increased from 0 to 3. The phenomena are attributed to the change of exchange interactions at FM/AFM interfaces due to the change of proportion of FM and AFM phases in low temperature magnetic states. The maximum exchange bias field H-E = 2.4 kOe at 10 K after field-cooling at 40 kOe is observed for Fe50Mn25Ga25. (C) 2013 Elsevier B.V. All rights reserved.
