The Search for Higher in Houston
C. W. Chu
It is a great pleasure to be invited to join the chorus on this auspicious occasion to celebrate Professor K. Alex Mueller's 90th birthday by Professors Annette Bussman-Holder, Hug…
Extremely large non-saturating magnetoresistance and ultrahigh mobility due to topological surface states in metallic Bi2Te3 topological insulator
K. Shrestha, M. Chou, D. Graf +3
Weak antilocalization (WAL) effects in Bi2Te3 single crystals have been investigated at high and low bulk charge carrier concentrations. At low charge carrier density the WAL curve…
Nearly ferromagnetic metal state in the collapsed tetragonal phase of YFe(Ge,Si)
J. Srpcic, P. Jeglic, I. Felner +3
The surprising discovery of tripling the superconducting critical temperature of KFeAs at high pressures issued an intriguing question of how the superconductivity in the c…
Chemical doping and high pressure studies of layered beta-PdBi2 single crystals
Kui Zhao, Bing Lv, Yu-Yi Xue +4
We have systematically grown large single crystals of layered compound beta-PdBi2, both the hole-doped PdBi2-xPbx and the electron-doped NaxPdBi2, and studied their magnetic and tr…
Magnetic field-induced spontaneous polarization reversal in multiferroic MnCoWO
N. Poudel, K. -C. Liang, Y. -Q. Wang +5
The magnetic and ferroelectric properties of the multiferroic system MnCoWO (x=0.135, 0.15, and 0.17) are studied in magnetic fields oriented along the monocl…
Superconductivity in the Mn5Si3-type Zr5Sb3 system
B. Lv, X. Y. Zhu, B. Lorenz +5
We report the discovery of superconductivity at 2.3 K in Zr5Sb3, the first superconducting member in the large compound family of the Mn5Si3-structure type. Transport, magnetic, an…
Incommensurate spin-density wave and multiband superconductivity in NaFeAs as revealed by nuclear magnetic resonance
M. Klanjsek, P. Jeglic, B. Lv +3
We report a Na and As nuclear magnetic resonance (NMR) investigation of NaFeAs series (, 0.9, 0.8) exhibiting a spin-density wave (SDW) order below $T_{\rm…
Magnetoelectricity and Magnetostriction due to the Rare Earth Moment in TmAl(BO)
R. P. Chaudhury, B. Lorenz, Y. Y. Sun +3
The magnetic properties, the magnetostriction, and the magnetoelectric effect in the d-electron free rare-earth aluminum borate TmAl(BO) are investigated between room t…
Evidence for multiple gaps in specific heat of LiFeAs crystals
F. Wei, F. Chen, K. Sasmal +5
The zero-field specific heat of LiFeAs was measured on several single crystals selected from a bulk sample. A sharp Delta Cp/Tc anomaly of approximately 20 mJ/(mole x K^2) was obse…
High Pressure Studies on Fe-Pnictide Superconductors
C. W. Chu, B. Lorenz
A review of high-pressure studies on Fe-pnictide superconductors is given. The pressure effects on the magnetic and superconducting transitions are discussed for different classes…

B. Lorenz, C. W. Chu
The review is devoted to a discussion of the effects of high pressure imposed on superconducting materials. Low-temperature superconductors, high-temperature superconducting cuprat…
Vortex avalanches and self organized criticality in superconducting niobium
E. Altshuler, T. H. Johansen, Y. Paltiel +6
In 1993 Tang proposed [1] that vortex avalanches should produce a self organized critical state in superconductors, but conclusive evidence for this has heretofore been lacking. In…
