Ternary-composition tuning of the anomalous Nernst effect in amorphous-like Gd-Co-Pt films
Tomohiro Koizumi, Mojtaba Mohammadi, Hiroto Imaeda +2
We report composition tuning of the anomalous Nernst effect in amorphous-like Gd-Co-Pt ternary films. Pt incorporation into Gd-Co films modifies the anomalous Nernst coefficient an…
Anomalous Nernst effect in amorphous Tb-Fe-Co thin films
Hiroto Imaeda, Tsunehiro Takeuchi, Hiroyuki Awano +1
We conducted a comprehensive study on the compositional dependence of the anomalous Nernst effect (ANE) in amorphous (amo.) Tb-Fe-Co thin films. The anomalous Nernst coefficient st…
Efficient spin-orbit torque driven magnetization switching of GdFe using phosphorus-implanted platinum layers
Kazuki Shintaku, Arun Jacob Mathew, Akihisa Iwamoto +4
The capability of the spin-orbit torque (SOT) generated via phenomena such as the spin Hall effect in heavy metals, in switching the magnetization of an adjacent magnetic material,…
Machine learning-based determination of magnetic parameters from magnetic images with different imaging scales
Akito Watanabe, Yoshinobu Nakatani, Hiroyuki Awano +1
The determination of material parameters is significantly important in material science, which is often a challenging task. Recently, advancements have shown that magnetic paramete…
Maximizing bipolar sensitivity for anomalous Nernst thermopiles in heat flux sensing in amorphous GdCo alloys
Miho Odagiri, Hiroto Imaeda, Ahmet Yagmur +4
A Heat Flux Sensor (HFS) facilitates the visualization of heat flow, unlike a temperature sensor, and is anticipated to be a key technology in managing waste heat. Recently, an HFS…
Significant improvement in sensitivity of an anomalous Nernst heat flux sensor by composite structure
Hiroto Imaeda, Reiji Toida, Tsunehiro Takeuchi +2
Heat flux sensors (HFS) have attracted significant interest for their potential in managing waste heat efficiently. A recently proposed HFS, that works on the basis of the anomalou…
