Ferroelectricity induced by ferriaxial crystal rotation and spin helicity in a B-site-ordered double-perovskite multiferroic In2NiMnO6
Noriki Terada, Dmitry D. Khalyavin, Pascal Manue +5
We have performed dielectric measurements and neutron diffraction experiments on the double perovskite In2NiMnO6. A ferroelectric polarization, P ~ 30 μC/m2, is observed in a polyc…
Inversion-induced orbital and exchange disorders in antiferromagnetic A-site spinel CoAl2O4
Takashi Naka, Hiroaki Mamiya, Kanji Takehana +6
The inversion and volume effects on magnetism in a spinel-type magnetically frustrated compound, CoAl2O4, and its gallium-substituted system, CoAl2-xGaxO4, were investigated. Magne…
Unusual coexistence of negative/positive charge-transfer in mixed-valence NaCaCrO
M. Taguchi, H. Yamaoka, Y. Yamamoto +6
We have investigated the electronic structure of NaCaCrO using x-ray absorption spectroscopy together with Anderson impurity model calculations with full multip…
Universal scaling in the dynamical conductivity of heavy fermion Ce and Yb compounds
H. Okamura, T. Watanabe, M. Matsunami +9
Dynamical conductivity spectra s(w) have been measured for a diverse range of heavy-fermion (HF) Ce and Yb compounds. A characteristic excitation peak has been observed in the mid-…
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…
