Spin-polarized angle-resolved photoelectron spectroscopy of the so-predicted Kondo topological insulator SmB6
Shigemasa Suga, Kazuyuki Sakamoto, Taichi Okuda +13
Undoped and slightly Eu-doped SmB6 show the opening of a gap with decreasing temperature below ~150 K. The spectral shapes near the Fermi level (EF) at 15 K have shown strong incre…
Superconducting order parameter in nonmagnetic borocarbides RNiBC (R=Y, Lu) probed by point-contact Andreev reflection spectroscopy
X. Lu, W. K. Park, S. Yeo +5
We report on the measurements of the superconducting order parameter in the nonmagnetic borocarbides LuNiBC and YNiBC. Andreev conductance spectra are obtained from…
Different Evolution of Intrinsic Gap in Kondo Semiconductors SmB6 and YbB12
J. Yamaguchi, A. Sekiyama, M. Y. Kimura +17
Dependence of the spectral functions on temperature and rare-earth substitution was examined in detail for Kondo semiconductor alloys Sm1-xEuxB6 and Yb1-xLuxB12 by bulk-sensitive p…
Concurrent Magnetic and Metal-Insulator Transitions in (Eu,Sm)B_6 Single Crystals
S. Yeo, J. E. Bunder, Hsiu-Hau Lin +2
The effects of magnetic doping on a EuB_6 single crystal were investigated based on magnetic and transport measurements. A modest 5% Sm substitution for Eu changes the magnetic and…
Torque magnetometry studies of new low temperature metamagnetic states in ErNi_{2}B_{2}C
D. G. Naugle, B. I. Belevtsev, K. D. D. Rathnayaka +2
The metamagnetic transitions in single-crystal ErNiBC have been studied at 1.9 K with a Quantum Design torque magnetometer. The critical fields of the transitions depend cr…
First order transition from correlated electron semiconductor to ferromagnetic metal in single crystalline FeSi1-xGex
S. Yeo, S. Nakatsuji, A. D. Bianchi +5
The phase diagram of FeSi1-xGex, obtained from magnetic, thermal and transport measurements on single crystals, shows a first-order transition from a correlated electron semiconduc…
