Conventional and inverse magnetocaloric effects, and critical behaviors in Ni43Mn46Sn8In3 alloy

Magnetic and magnetocaloric properties of Ni-Ag-Mn-Sn ribbons and their composites

“…In comparison to the theoretical models [19,21] and the results obtained for the austenitic phase in the recently reports [14,15,22] (Table 2), the values of the critical exponents obtained for our samples are …”

“…It does not affect the actual construction M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 15 of the universal curve, as it implies only proportionality constant [32,33]. The collapse of the ∆S m (T, H) data into a single curve for θ > 0 is due to the PM behavior.…”

“…For comparison, Table 3 shows the values of |∆S max |/∆H and RCP/∆H for our samples compared with those obtained from Gd [6] and some Ni-Mn-Heusler systems [8,14,15,22,[28][29][30][31], which recently reported about the near room-temperature MCE. Fig.…”

“…Krenke and coworkers [16] also showed that the phase diagram of structural and magnetic transition temperatures as a function of the electrons per atom ratio. Besides, there is a highly agree of magnetically inhomogeneous in the martensitic phase due to the coexistence of anti-FM/FM cluster [15,16]. In a previous report, Phan and coworkers [14] showed that the Sn-content may drive the ferromagnetic (FM) austenitic phase in the Ni-Mn-Sn system, from the shortrange FM order for Ni 50 Mn 37 Sn 13 to long-range FM order for Ni 50 Mn 36 Sn 14 .…”

“…They have been found to be strongly correlated with the composition. Ni-Mn-X systems usually exhibit a number of interesting features associated with structural and multiple magnetic phase transitions, which are associated with the coexistence of the martensitic and the austenitic phases [8][9][10][11][13][14][15]. These alloys may undergo the following consecutive phase transitions, including a magnetic SOPT in the martensitic phase, a magnetostructural FOPT from the martensitic phase to the austenitic phase (at the temperature T M-A ) that involves a change in both structural and magnetic properties of the material, and a second magnetic SOPT in the austenitic phase at the temperature T C .…”
