A fundamental challenge of the quantum revolution is to efficiently interface the quantum computing systems operating at cryogenic temperatures with room temperature electronics an…
Large Enhancement of Critical Current in Superconducting Devices by Gate Voltage
Mirko Rocci, Dhavala Suri, Akashdeep Kamra +5
The gate-voltage-induced suppression of critical currents in metallic superconductors observed recently [De Simoni et al., Nat. Nanotechnol. 13, 802 (2018)] has raised crucial ques…
Methods to induce perpendicular magnetic anisotropy in full-Heusler Co2FeSi thin layers in a magnetic tunnel junction structure
Koki Shinohara, Takahiro Suzuki, Yota Takamura +1
In this study, to obtain perpendicular magnetic tunnel junctions (p-MTJs) using half-metallic ferromagnets (HMFs), several methods were developed to induce perpendicular magnetic a…
