Research Abstract

We primarily intended to develop the specific heat measurements in pulsed magnetic field using Flywheel generator. However, since the use of the Flywheel generator became limited because of the power restriction due to the Great East Japan Earthquake, we necessitated a change in the plan and performed the magnetization andmagnetoresistance measurements of Kondo semiconductor CeT2Al10(T=Ru,Os)in pulsed high magnetic filed. We found that an anisotropic large hybridization between theconduction band and the nearly localized 4f shell plays an important role in this system.
