XRD analyses performed at room temperature showed that the main sample was in martensite phase, while x = 3 sample was in L2(1) structure which is attributed to austenite phase. The samples exhibited a first-order structural transformation from austenite phase to martensite phase. The martensitic transformation (MT) temperature was reduced by increasing the amount of V. Besides, V doping caused an increase in magnetization. Although antiferromagnetic interactions arising from Mn-Mn couplings were effective at low temperatures, they vanished above the blocking temperature. Magnetic entropy change (Delta S-M) of the samples was estimated using the Maxwell equation from isothermal magnetization curves. An inverse magnetocaloric effect was observed around the MT interval and Delta S-M was significantly improved with increasing V content and applied magnetic field. Maximum refrigerant capacity (RC), which is one of the quality parameters for characterizing a magnetic refrigerant, was determined as 96.7 J/kg for x = 3 samples (Delta H = 5 T).eninfo:eu-repo/semantics/closedAccessMagnetic shape memoryInverse magnetocaloric effectExchange bias effectFirst-order structural transitionArticle35113323333110.1007/s10948-022-06396-12-s2.0-85137821576Q3WOS:000852105500001Q3
