Relatively large temperature decrease with hysteresis is observed at just below the $\\beta$-$\\gamma$ and $\\alpha$-$\\beta$ phase transition temperatures owing to the field-induced transitions. The magnetic field dependences of these phase boundaries are obtained as $T_\\mathrm{\\beta\\gamma}(H)=43.8-1.55\\times10^{-3}H^2$ K and $T_\\mathrm{\\alpha\\beta}(H)=23.9-0.73\\times10^{-3}H^2$ K.
