Modulation of Spin Accumulation by Nanoscale Confinement using Electromigration in a Metallic Lateral Spin Valve
Emmanouil Masourakis, Libe Arzubiaga, Goran Mihajlović +4
We study spin transport in lateral spin valves with constricted channels. Using electromigration, we modulate the spin accumulation by continuously varying the width of the non-mag…
Reliable determination of the Cu/n-Si Schottky barrier height by using in-device hot-electron spectroscopy
Subir Parui, Ainhoa Atxabal, Mário Ribeiro +5
We show the operation of a Cu/Al_2O_3/Cu/n-Si hot-electron transistor for the straightforward determination of a metal/semiconductor energy barrier height even at temperatures belo…
Spin Hall magnetoresistance as a probe for surface magnetization in Pt/CoFeO bilayers
Miren Isasa, Saül Vélez, Edurne Sagasta +6
We study the spin Hall magnetoresistance (SMR) in Pt grown on CoFeO (CFO) ferrimagnetic insulating (FMI) films. A careful analysis of the angle-dependent…
Magnetic anisotropy in Shiba bound states across a quantum phase transition
Nino Hatter, Benjamin W. Heinrich, Michael Ruby +2
The exchange coupling between magnetic adsorbates and a superconducting substrate leads to Shiba states inside the superconducting energy gap and a Kondo resonance outside the gap.…
Near-field photocurrent nanoscopy on bare and encapsulated graphene
Achim Woessner, Pablo Alonso-González, Mark B. Lundeberg +14
Opto-electronic devices utilizing graphene have already demonstrated unique capabilities, which are much more difficult to realize with conventional technologies. However, the requ…
One-dimensional spin texture of Bi(441); Quantum Spin Hall properties without a topological insulator
M. Bianchi, F. Song, S. Cooil +11
The high index (441) surface of bismuth has been studied using Scanning Tunnelling Microscopy (STM), Angle Resolved Photoemission Spectroscopy (APRES) and spin-resolved ARPES. The…
