Visualizing impurity-driven scattering phase textures in EuCd2As2

Raquel Sánchez-Barquilla, R. A. Medina, Pablo García Talavera, Adrian Valadkhani et autres

Understanding how disorder modifies electronic states in magnetic semiconductors is important for controlling spin-dependent transport and topological responses. Here we use scanning tunneling microscopy to visualize scattering phase textures in EuCd2As2. By isolating a single surface wavevector we reconstruct spatial phase maps …

Linear Magnetic Field Suppression of the Superconducting Gap in NbTi and MgB$$_2$$ Wires

Jaime Rumeu Ozores, Oscar Bou Marqués, Jose Antonio Moreno, Daniel Gajda et autres

Abstract Superconducting vortices have a normal core and are pinned at imperfections, facilitating large current flow. Applications such as high-field solenoids or superconducting motors rarely use pure materials, as these are brittle, and instead employ superconductors embedded in ductile matrices (e.g., Cu …

Direct Observation of Vortex Liquid Droplets in the Iron Pnictide Superconductor CaKFe 4 As 4 at 0.5T c

Oscar Bou Marqués, Jose Antonio Moreno, Pablo García Talavera, Mingyu Xu et autres

ABSTRACT Type‐II superconductors under magnetic fields remain in a quantum‐coherent, non‐dissipative state as long as vortices are pinned. Dissipation emerges when vortices depin, a process often driven by thermal fluctuations and commonly associated with a melting transition from a vortex solid to …

Robust Two-Dimensional Surface Superconductivity and Vortex Lattice in the Weyl Semimetal γ − PtBi 2

Anonymous, Pablo García Talavera, Edwin Herrera, Sara López Valle et autres

The layered compound γ-PtBi_{2} is a topological semimetal with Fermi arcs at the surface joining bulk Weyl points. Recent work has found signatures of surface superconductivity consisting of gap openings compatible with a critical temperature orders of magnitude larger than the bulk …

Scanning Tunneling Microscopy in high vectorial magnetic fields

Jaime Rumeu Ozores, Miguel Águeda Velasco, Edwin Herrera, Pablo García Talavera et autres

The Scanning Tunneling Microscope (STM) is a powerful instrument to measure electronic density of states at surfaces down to atomic scale. Many systems of interest require studying variations as a function of the magnetic field, which is most often applied perpendicular to …

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe 2‐ x S x

Jose Antonio Moreno, Mercè Roig, Víctor Barrena, Edwin Herrera et autres

ABSTRACT Most superconducting materials exhibit a vanishing density of states at the Fermi level and Anderson's theorem posits that the superconducting gap is robust against nonmagnetic disorder. Although dilute magnetic impurities lead to localized in‐gap states, these states typically have no bearing …
