Many rules have been suggested to rationalize the behaviour of transition metal oxides but the complex underlying physics often leads to deviations from the expected behaviour. Here the authors show that the metal-insulator transition in CsW2O6 satis

Cyclotron resonance (CR) in AlGaN/GaN two-dimensional electron system is investigated under high magnetic fields up to 15 T in order to study the magnetic field dependence of the electron effective mass. Non-linear dependence of the CR energy against

Since the discovery of the Verwey transition in magnetite, transition metal compounds with pyrochlore structures have been intensively studied as a platform for realizing remarkable electronic phase transitions. We report on a phase transition that p

Logarithmical increase of the longitudinal resistivity ( ρ x x ) between 10 K and 80 K and its saturation at low temperature were observed in the graphene synthesized by the chemical vapor deposition (CVD) with various applied gate voltage. In the t

We investigate phenomena correlated with multiple degrees of freedom in a geometrically frustrated magnet, ${\mathrm{CuFeO}}_{2}$, by applying uniaxial pressure $p$ and magnetic field $H$. Ferroelectric polarization is induced by a combination of $p$

Observations of fractional quantum Hall (FQH) plateaus are reported in bilayer electron gas system in wide (>80 nm) In0.75Ga0.25As wells. Several q/p (p = 5, 3, and 2, q > 5) QH states are confirmed at high temperatures (~1.6 K) when the critical con

We find magnetic-field-dependent dielectric dispersions specific to successive field-induced magnetic phases of a geometrically frustrated magnet ${\mathrm{CuFeO}}_{2}$ up to 28 T. The dielectric dispersions in the three field-induced collinear-comme

TlMO(3) perovskites (M(3+) = transition metals) are exceptional members of trivalent perovskite families because of the strong covalency of Tl(3+)-O bonds. Here we report on the synthesis, crystal structure and properties of TlCrO(3) investigated by

Cyclotron resonance has been investigated on single-layer large-area graphene which was synthesized by chemical vapor deposition. Absorption peaks of the cyclotron resonance are clearly observed on the graphene sample and these peak energies exhibit
