Field-induced magnetic ordering in the Haldane system PbNi2V2O8
N. Tsujii, O. Suzuki, H. Suzuki +2
The Haldane system PbNi2V2O8 was investigated by the temperature dependent magnetization M(T) measurements at fields higher than H_c, with H_c the critical fields necessary to clos…
Universality in heavy-fermion systems with general degeneracy
N. Tsujii, H. Kontani, K. Yoshimura
We discuss the relation between the T^{2}-coefficient of electrical resistivity and the T-linear specific-heat coefficient for heavy-fermion systems with general , where…
Magnetic properties and thermal expansion of YbGaGe (0.9 <= x <= 1.5)
N. Tsujii, T. Furubayashi, H. Kitazawa +1
The composition dependence of the Yb valence and of the thermal expansion have been studied in the YbGaGe system. X-ray diffraction reveals that single-phased samples i…
Deviation from the Kadowaki-Woods relation in Yb-based intermediate-valent systems
N. Tsujii, K. Yoshimura, K. Kosuge
The T^2 coefficient of electrical resistivity, A, is compared with the electronic specific-heat coefficient, γ, for a number of Yb-based compounds. It is revealed that many systems…
High-field magnetization of the 3d heavy-fermion system LiVO (d = 0, 0.08)
N. Tsujii, K. Yoshimura, K. Kosuge +2
Metamagnetic behavior has been observed in LiV2O4 powder sample around 38 T at 4.2 K. On the other hand, magnetization for oxygen deficient LiV2O3.92 shows no indication of metamag…
