Microscopic Insights into London Penetration Depth: Application to CeCoIn
Mehdi Biderang, Jeehoon Kim, Reza Molavi +1
We propose a comprehensive theoretical formulation of magnetic penetration depth, , based on the microscopic calculations for a general superconducting gap symmetry. Our find…
Local characterization of a heavy-fermion superconductor via sub-Kelvin magnetic force microscopy
Dirk Wulferding, Geunyong Kim, Hoon Kim +5
Using magnetic force microscopy operating at sub-Kelvin temperatures we characterize the heavy-fermion superconductor CeCoIn. We pinpoint the absolute London penetration depth…
Josephson coupling in high-T superconducting junctions using ultra-thin BaTiO barriers
H. Navarro, M. Sirena, Jeehoon Kim +1
We study the electrical transport of vertically-stacked Josephson tunnel junctions using GdBaCuO electrodes and a BaTiO barrier with thicknesses between 1 nm an…
Spatially resolved penetration depth measurements and vortex manipulation in the ferromagnetic superconductor ErNi2B2C
Dirk Wulferding, Ilkyu Yang, Jinho Yang +6
We present a local probe study of the magnetic superconductor, ErNiBC, using magnetic force microscopy at sub-Kelvin temperatures. ErNiBC is an ideal system to expl…
Single Vortex Pinning and Penetration Depth in Superconducting NdFeAsOF
Jessie T. Zhang, Jeehoon Kim, Magdalena Huefner +6
We use a magnetic force microscope (MFM) to investigate single vortex pinning and penetration depth in NdFeAsOF, one of the highest- iron-based superconductors. In…
Weak pinning and vortex bundles in anisotropic Ca(PtAs)[(FePt)As] single crystals
O. E. Ayala-Valenzuela, N. Haberkorn, A. B. Karki +3
We report the magnetic field -- temperature () phase diagram of Ca(PtAs)[(FePt)As] () single crystals, which consists of…
