| 内容記述 | The electrical resistivity and ac magnetic susceptibility of the heavy-fermion compound Ce7Ni3 were measured in the temperature range from 0.4 to 300 K and in the pressure range up to 1.5 GPa. The Ne?el temperature of 1.9 K for antiferromagnetic transition at ambient pressure decreases with increasing pressure and vanishes at about 0.33 GPa. The magnetic resistivity, ρm=ρ(Ce7Ni3)-ρ(La 7Ni3), decreases steeply with pressure, and above 0.66 GPa, ρm(T) can be described by the expression ρm(T)=ρm(0)+AT2. The coefficient A decreases and the temperature range in which the T2 dependence is held becomes wider with increasing pressure. The electronic Gru?neisen parameter for the Kondo temperature TK, -∂lnTK/∂lnV, is evaluated to be 132 from the pressure dependence of A. This value is larger than that of typical heavy-fermion compounds. The results are discussed in relation to the competition between the magnetic interaction and the Kondo interaction in Ce7Ni3. | |||||||||||
