We report the transport and thermodynamic properties under hydrostatic pressure in the antiferromagnetic Kondo compound CeMg2Cu9 with a two-dimensional arrangement of Ce atoms. Magnetic specific heat Cmag(T) shows a Schottky-type anomaly around 30 K

We studied the magnetic properties of RuSr 2 (Gd 2-x Ce x )Cu 2 O 10 . In the temperature dependence of magnetic susceptibility, we observed a ferromagnetic increase and an anomalous oscillating behavior below T M . In ESR measurements, we observed a

Ultrasonic measurements have been performed on high quality single crystals of Sr 2 RuO 4 across the superconducting transition temperature T c (≈1.37 K). A discontinuous jump at T c was observed in a longitudinal elastic modulus C 11 as is seen in

We report on magnetic-history dependent magnetoresistance in UNiAl at various temperatures. The magnetic-field (applied along the c-axis) induced irreversibility of magnetoresistance is strongest at the lowest temperature of measurement (0.5 K) and d

The in-plane optical conductivity of three metallic La2−x Sr x CuO4 single crystals with 0.10 ≤ x ≤ 0.15 has been studied between 30 and 295 K. Strong peaks in the far-infrared are observed, which cannot be explained by Drude-like models. Their

Tunneling measurements have been carried out on the extremely underdoped La1−xSrxCuO4 (LSCO) single crystal with x = 0.02. The break junction was employed to obtain the reliable tunneling spectra from surface sensitive LSCO. The gap width is obtain

We have observed visible light emission by tunneling Cooper pairs across the vacuum gap of a scanning tunneling microscope (STM) formed by a Nb tip and a Nb sample at 4.7 K. Besides the usual STM light emission that is excited by single electron tunn
