Ultra‐High Spin Hall Angle in Sputtered Sb2Te3 Topological Insulators via Pt Interfacial Engineering

Advanced Physics Research, EarlyView.
Topological insulator Sb2Te3 demonstrates exceptional charge‐to‐spin conversion efficiency and thermal stability up to 400°C, showing great promise for spin–orbit torque memory applications. This study achieves high‐quality Sb2Te3 films on silicon substrates through optimized sputtering and introduces an ultrathin Pt interlayer to suppress interfacial ...

Magnetic Solitons and Thickness‐Dependent Magnetization Reversal in Interconnected Helical Nanowire Arrays

Advanced Physics Research, EarlyView.
3D magnetic interconnected helical nanowire arrays are fabricated and shown to host a variety of magnetic solitons. It is observed that the magnetic reversal mechanism is repeatable and not stochastic for a consistent direction of the applied field. Additionally, changing the shape of the nanowire arrays alters the magnetic solitons that form, but the ...

Structural, Superconducting and Magnetic Properties of Oxygen‐Annealed Fe1+yTe Thin Films

Advanced Physics Research, EarlyView.
FeTe:Ox films exhibit exchange bias below their Néel temperatures, which coexists with superconductivity. STEM analysis reveals the structural changes induced by oxygen treatment. DFT calculations indicate that interstitial oxygen suppresses antiferromagnetism and promotes superconductivity.

Controlling Bubble and Skyrmion Lattice Order and Dynamics via Stripe Domain Engineering in Ferrimagnetic Fe/Gd Multilayers

Advanced Physics Research, EarlyView.
The density and ordering of the bubble/skyrmion lattice hosted by Fe/Gd multilayers can be significantly enhanced using an in‐plane field to align the stripe domain state. As a result, the laser‐induced breathing mode dynamics are strongly modified, showing both an increased amplitude and frequency.
