High temperature martensitic transformation and giant magnetocaloric effect in Ni40Co10Mn41Sn9 melt-spun ribbons
Chen, F. (2018-05-05)We report a large magnetic entropy change associated with a high-temperature martensitic transformation in Ni40Co10Mn41Sn9 (at. %) melt-spun ribbons. The ribbons underwent a first-order forward martensitic transition and ... -
Influence of γ phase on the magnetostructural transition and magnetocaloric properties in Ni38Co12Mn41Sn9 melt-spun ribbons
Sánchez Valdés, César Fidel; Chen, F.; Sánchez Llamazares, J.L.; Müllner, P.; Tong, Y.X.; Li, L. (2023-06-05)In the present work, Ni38Co12Mn41Sn9 melt-spun ribbons were annealed under different conditions to make samples free of secondary γ phase precipitates or get them with various average grain sizes. A comparative study was ... -
Large magnetic entropy change and refrigeration capacity around room temperature in quinary Ni41Co9-xFexMn40Sn10 alloys (x= 2.0 and 2.5)
Sánchez Valdés, César Fidel (2020-06-05)We report the magnetocaloric properties of two Fe-containing quinary bulk polycrystalline alloys of nominal compositions Ni41Co7Fe2Mn40Sn10 and Ni41Co6.5Fe2.5Mn40Sn10 that were determined by indirect and direct methods. ... -
Wide structural and magnetic successive transitions and related magnetocaloric properties in a directionally solidified polycrystalline Ni-Co-Mn-In alloy
Sánchez Valdés, César Fidel; Chen, F.; Sánchez Llamazares, J. L.; Müllner, P.; Tong, Y. X.; Li, L. (2020-02-21)We fabricated a Ni45Co6.4Mn37In11.6 polycrystalline sample with a specific texture by directional solidification. The alloy is characterized by wide successive structural and magnetic phase transitions that considerably ...
