Two-band effect on the vortex dynamics and critical current density in an anisotropic MgB thin film
Jeehoon Kim, N. Haberkorn, E. Nazaretski +5
We report the influence of intrinsic superconducting parameters on the vortex dynamics and the critical current densities of a MgB thin film. The small magnetic penetration dep…
Honeycomb lattice of graphite probed by scanning tunneling microscopy with a carbon nanotube tip
Jeehoon Kim, Junwei Huang, Alex de Lozanne
A carbon nanotube (CNT) tip was fabricated at the apex of an etched tungsten wire by chemical vapor deposition and used for scanning tunneling microscopy. The honeycomb lattice of…
Observation of electronic inhomogeneity and charge density wave in a bilayer LaSrMnO single crystal
Jeehoon Kim, Junwei Huang, J. -S. Zhou +3
We employed a scanning tunneling microscope to image the (001) surface topography and local density of states (LDOS) in LaSrMnO (x=0.32, LSMO) single crys…
Effects of pressure on the ferromagnetic state of the CDW compound SmNiC2
B. Woo, S. Seo, E. Park +8
We report the pressure response of charge-density-wave (CDW) and ferromagnetic (FM) phases of the rare-earth intermetallic SmNiC2 up to 5.5 GPa. The CDW transition temperature (T_{…
Intrinsic superconducting properties and vortex dynamics in heavily overdoped Ba(FeCo)As single crystal
Jeehoon Kim, N. Haberkorn, K. Gofryk +5
In this work we report the influence of intrinsic superconducting parameters on the vortex dynamics in an overdoped Ba(FeCo)As (x=0.14) single crystal. We find…
Strong Enhancement of the Critical Current at the Antiferromagnetic Transition in ErNi2B2C Single Crystals
M. Weigand, L. Civale, F. J. Baca +4
We report on transport and magnetization measurements of the critical current density Jc in ErNi2B2C single crystals that show strongly enhanced vortex pinning at the Neel temperat…
