Monitoring Mechanical Motion of Carbon Nanotube based Nanomotor by Optical Absorption Spectrum
Baomin Wang, Xuewei Cao, Zhan Wang +2
The optical absorption spectrums of nanomotors made from double-wall carbon nanotubes have been calculated with the time-dependent density functional based tight binding method. Wh…
Significant enhancement of upper critical fields by doping and strain in Fe-based superconductors
C. Tarantini, A. Gurevich, J. Jaroszynski +7
We report measurements of Hc2(T) up to 85 Tesla on Ba1-xKxAs2Fe2 single crystals and FeSe1-xTex films tuned by doping and strain. We observed an Hc2 enhancement by nearly 25 T at 3…
Magnetic ordering of the RE lattice in REFeAsO: the odd case of Sm. A specific heat investigation in high magnetic field
S. Riggs, C. Tarantini, J. Jaroszynski +5
We have investigated the evolution of the low temperature specific heat anomaly (TN=5.4K in zero field) in polycrystalline SmFeAsO samples with magnetic fields up to 35T. The anoma…
High-field phase-diagram of Fe arsenide superconductors
Y. J. Jo, J. Jaroszynski, A. Yamamoto +13
Here, we report an overview of the phase diagram of single layered and double layered Fe arsenide superconductors at high magnetic fields. Our systematic magnetotransport measureme…
An Intermediate Phase at the Metal-Insulator Boundary in a Magnetically Doped Two-Dimensional Electron System
J. Jaroszynski, T. Andrearczyk, G. Karczewski +4
A magnetotransport study in magnetically doped (Cd,Mn)Te 2D quantum wells reveals an apparent metal-insulator transition as well as an anomalous intermediate phase just on its meta…
Effects of Spin Polarization on Electron Transport in Modulation Doped Cd(1-x)Mn(x)Te/Cd(1-y)Mg(y)Te:I Heterostructures
T. Andrearczyk, J. Jaroszynski, G. Karczewski +6
We examine and identify magnetoresistance mechanisms in 2D system containing a sizable concentration of magnetic ions. We argue that some of these mechanisms can serve as a tool to…
