Half-ordered state in the anisotropic Haldane-gap antiferromagnet NDMAP
A. Zheludev, B. Grenier, E. Ressouche +2
Neutron diffraction experiments performed on the Haldane gap material NDMAP in high magnetic fields applied at an angle to the principal anisotropy axes reveal two consecutive fiel…
Optical conductivity of filled skutterudites
Tetsuya Mutou, Tetsuro Saso
A simple tight-binding model is constructed for the description of the electronic structure of some Ce-based filled skutterudite compounds showing an energy gap or pseudogap behavi…
Calculation of Optical Conductivity of YbB using Realistic Tight-Binding Model
Tetsuro Saso
Based on the previously reported tight-binding model fitted to the LDA+U band calculation, optical conductivity of the prototypical Kondo insulator YbB is calculated theoret…
High-field phase diagram of the Haldane-gap antiferromagnet
H. Tsujii, Z. Honda, B. Andraka +2
We have determined the magnetic phase diagram of the quasi-one-dimensional 1 Heisenberg antiferromagnet by specific heat measurements to 150…
Real Space Renormalization Group Study of the S=1/2 XXZ Chains with Fibonacci Exchange Modulation
Kazuo Hida
Ground state properties of the S=1/2 antiferromagnetic XXZ chain with Fibonacci exchange modulation are studied using the real space renormalization group method for strong modulat…
Uniaxial-Pressure induced Ferromagnetism of Enhanced Paramagnetic Sr3Ru2O7
Shin-Ichi Ikeda, Naoki Shirakawa, Takashi Yanagisawa +5
We report a uniaxial pressure-dependence of magnetism in layered perovskite strontium ruthenate Sr3Ru2O7. By applying a relatively small uniaxial pressure, greater than 0.1 GPa nor…
New Universality Class in the S=1/2 Fibonacci Heisenberg Chains
Kazuo Hida
Low energy properties of the S=1/2 antiferromagnetic Heisenberg chains with Fibonacci exchange modulation are studied using the real space renormalization group method for strong e…
Observation of a Transient Magnetization Plateau in a Quantum Antiferromagnet on the Kagome Lattice
Y. Narumi, K. Katsumata, Z. Honda +6
The magnetization process of an S=1/2 antiferromagnet on the kagome lattice, [Cu_3(titmb)_2(OCOCH_3)_6]H_2O {titmb= 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6 trimethylbenzene} has been…
Bond Operator Mean Field Approach to the Magnetization Plateaux in Quantum Antiferromagnets -- Application to the S=1/2 Coupled Dimerized Zigzag Heisenberg Chains
Kazuo Hida, Masaru Shiino, Wei Chen
The magnetization plateaux in two dimensionally coupled S=1/2 dimerized zigzag Heisenberg chains are investigated by means of the bond operator mean field approximation. In the abs…
