Minimal Damage and Tunable Fabrication of Atomic‐Scale Ultrathin YBa2Cu3O7‐δ Nanowires with High Uniformity

Small Structures, Volume 6, Issue 5, May 2025.
Herein, the fabrication of high‐quality, ultrathin, and ultranarrow YBa2Cu3O7‐δ (YBCO) nanowires with minimal damage (≈15 nm) and excellent uniformity, achieved through protective layers and precise etching, is demonstrated. These advances overcome challenges in high‐temperature superconducting devices, paving the way for YBCO‐based superconducting ...

Investigation of the Dzyaloshinskii-Moriya interaction and room temperature skyrmions in W/CoFeB/MgO thin films and microwires

, 2017
Recent studies have shown that material structures, which lack structural inversion symmetry and have high spin-orbit coupling can exhibit chiral magnetic textures and skyrmions which could be a key component for next generation storage devices.
