Title: Magnetic hysterysis evolution of Ni-Al alloy with Fe and Mn substitution by vacuum arc melting to produce the room temperature magnetocaloric effect material

Abstract

The development of magnetocaloric effect (MCE) material is done in order to reduce the damage of the ozone layer caused by the chlorofluorocarbons (CFCs) emitted into the air. The research dealing with synthesis of magnetocaloric materials based of Ni-Al Heusler Alloy structure and by varying substitution some atoms of Ni with Fe and Al with Mn on Ni-Al Heusler Alloy structure to become Ni{sub 44}Fe{sub 6}Mn{sub 32}Al{sub 18}. Vacuum Arc Melting (VAM) equipment is used to form the alloys on vacuum condition and by flowing argon gas atmosphere and then followed by annealing process for 72 hours. X-Ray Diffraction (XRD) reveals that crystallite structure of material is observed. We define that Ni{sub 44}Fe{sub 6} as X{sub 2}, Mn{sub 25} as Y, and Al{sub 18}Mn{sub 7} as Z. Based on the XRD result, we observed that the general formula X{sub 2}YZ is not changed. The PERMAGRAF measurement revealed that there exists of magnetic hysterysis. The hysterysis show that the magnetic structures of the system undego evolution from diamagnetic to soft ferromagnetic material which all of the compound have the same crystallite structure. This evolution indicated that the change in the composition has led to changes the magnetic composition. Mn is themore » major element that gives strong magnetic properties to the sample. When Mn partially replaced position of Al, the sample became dominant to be influenced to improve their magnetic properties. In addition, substitution a part of Ni by Fe in the composition reveals a pinning of the domain walls in the sample.« less

  • The magnetic and magnetocaloric properties of Ni{sub 48}Co{sub 2}Mn{sub 35}In{sub 15} were studied using magnetization and heat capacity measurements. The magnetic entropy change ({Delta}S{sub M}) was evaluated from both magnetizing and demagnetizing fields. An inverse {Delta}S{sub M} for the magnetizing and demagnetizing processes were found to be 20.5 and 18.5 J kg{sup -1} K{sup -1}, respectively, for {Delta}H = 5 T at the martensitic transition (T = T{sub M}). The normal {Delta}S{sub M} was found to be -5.4 J kg{sup -1} K{sup -1} for both fields at the paramagnetic/ferromagnetic transition (T = T{sub C}). The effective refrigeration capacity at T{submore » M} and T{sub C} for magnetizing field was found to be 268 and 243 J/kg (285 and 243 J/kg for the demagnetizing field), respectively. We have also estimated the density of states, the Debye temperature, and the inverse adiabatic temperature change to be 4.93 states/eV f.u., 314 K, and -3.7 K, respectively, from the measured heat capacity data.« less
  • The low-temprature heat capacity and ac and dc magnetic properties of (Dy[sub 0.5]Er[sub 0.5])Al[sub 2] have been studied as a function of magnetic fields up to [similar to]10 T. The magnetocaloric effect in (Dy[sub 0.5]Er[sub 0.5])Al[sub 2] is 30% larger than that of the prototype material, GdPd. Magnetic measurements show that there is no measurable magnetic hysteresis above [similar to]17 K. These results suggest that (Dy[sub 0.5]Er[sub 0.5])Al[sub 2] would be a significantly better magnetic refrigerant than GdPd.
  • We have studied the effect of magnetic field on a nonstoichiometric Heusler alloy Ni{sub 50}Mn{sub 35}In{sub 15} that undergoes a martensitic as well as a magnetic transition near room temperature. Temperature dependent magnetization measurements demonstrate the influence of magnetic field on the structural phase transition temperature. From the study of magnetization as a function of applied field, we show the occurrence of inverse-magnetocaloric effect associated with this magneto-structural transition. The magnetic entropy change attains a value as high as 25 J/kg K (at 5 T field) at room temperature as the alloy transforms from the austenitic to martensitic phase withmore » a concomitant magnetic ordering.« less
