Research Abstract

We developed high-speed measurements of sample temperature in pulsed high magnetic fields. In pulsed magnetic fields, we can easily achieve adiabatic magnetization process because of the small heat exchange between the sample and thermal bath in the short duration of pulsed field. Thus, we established reliable measurements of magneto-caloric effects in pulsed fields up to 55 T. With using this system, we measured magneto-caloric effects in magnetic shape memory alloys, which has been regarded to show large inverse magneto-caloric effects. Our experimental results clarified the direct evidence of this effect for the first time. In addition, through careful discussion on the results, we succeeded in evaluating each contribution of spin, charge, and lattice to this effect, and concluded the lattice sector showed the largest contribution to this effect.
