Cyclotron resonance and mass enhancement by electron correlation in KFeAs
Motoi Kimata, Taichi Terashima, Nobuyuki Kurita +15
Cyclotron resonance (CR) measurements for the Fe-based superconductor KFeAs are performed. One signal for CR is observed, and is attributed to the two-dimensional Fermi…
Large Magnetic Susceptibility Anisotropy of Metallic Carbon Nanotubes
T. A. Searles, Y. Imanaka, T. Takamasu +4
Through magnetic linear dichroism spectroscopy, the magnetic susceptibility anisotropy of metallic single-walled carbon nanotubes has been extracted and found to be 2-4 times great…
Possible Phase Transition Deep Inside the Hidden Order Phase of Ultraclean URu2Si2
H. Shishido, K. Hashimoto, T. Shibauchi +10
To elucidate the underlying nature of the hidden order (HO) state in heavy-fermion compound URu2Si2, we measure electrical transport properties of ultraclean crystals in a high fie…
Effect of charge state in nearby quantum dots on quantum Hall effect
K. Takehana, T. Takamasu, G. Kido +1
Magnetoresistance measurements have been performed on a gated two-dimensional electron system (2DES) separated by a thin barrier layer from a layer of InAs self-assembled quantum d…
Field-Induced Magnetic Ordering in the Quantum Spin System KCuCl
A. Oosawa, T. Takamasu, K. Tatani +6
KCuCl is a three-dimensional coupled spin-dimer system and has a singlet ground state with an excitation gap K. High-field magnetization measurements for KCuCl…
Spin-phonon coupled modes in the incommensurate phases of doped CuGeO
K. Takehana, T. Takamasu, M. Hase +3
The doping effect of the folded phonon mode at 98 cm was investigated on the Si-doped CuGeO by magneto-optical measurements in far-infrared (FIR) region under high magne…
Far-Infrared Spectroscopy in Spin-Peierls Compound CuGeO_3 under High Magnetic Fields
K. Takehana, T. Takamasu, M. Hase +2
Polarized far-infrared (FIR) spectroscopic measurements and FIR magneto-optical studies were performed on the inorganic spin-Peierls compound CuGeO_3. An absorption line, which was…
