We developed a high-speed and low-noise time-domain current measurement scheme using a homemade GaAs high-electron-mobility-transistor-based cryogenic transimpedance amplifier (TIA). The scheme is versatile for broad cryogenic current measurements, i

We report a cryogenic transimpedance amplifier (TA) suitable for cross-correlation current-noise measurements. The TA comprises homemade high-electron-mobility transistors with high transconductance and low noise characteristics, fabricated in an AlG

Magnetic field and spin-orbit interaction (SOI) are representative freedoms that can be entangled to electron spins. In experiments, while magnetic field strong enough for the control of spin is difficult to be localized onto the area for single spin

The valence transition temperature, T v , of YbInCu 4 was found to increase substantially by substitution of Ag for In. From the nuclear magnetic resonance of 115 In, we observed the drastic change in the coupling between 4f and conduction electrons

Mixed-valence ${\mathrm{YbCu}}_{2}$ has been studied by x-ray and ultraviolet photoemission spectroscopy (XPS and UPS). UPS results reveal a bulk divalent (4${f}^{14}$\ensuremath{\rightarrow}4${f}^{13}$) peak \ensuremath{\sim}0.3 eV below the Fermi l
