Above-room-temperature giant thermal conductivity switching in spintronic multilayer
Hiroyasu Nakayama, Bin Xu, Sotaro Iwamoto +8
Thermal switching provides an effective way for active heat flow control, which has recently attracted increasing attention in terms of nanoscale thermal management technologies. I…
Theory of Transport in Ferroelectric Capacitors
Gerrit E. W. Bauer, Ryo Iguchi, amd Ken-ichi Uchida
We present a time-dependent diffusion theory for heat and polarization transport in a planar ferroelectric capacitor with parameters derived from a one-dimensional phonon model. We…
High-temperature dependence of anomalous Ettingshausen effect in SmCo-type permanent magnets
Asuka Miura, Keisuke Masuda, Takamasa Hirai +6
The anomalous Ettingshausen effect (AEE) in SmCo-type permanent magnets has been investigated in the high-temperature range from room temperature to around 600 K. The anomalous…
Probing thermal magnon current mediated by coherent magnon via nitrogen-vacancy centers in diamond
Dwi Prananto, Yuta Kainuma, Kunitaka Hayashi +3
Currently, thermally excited magnons are being intensively investigated owing to their potential in computing devices and thermoelectric conversion technologies. We report the dete…
Perpendicularly Magnetized Ni / Pt (001) Epitaxial Superlattice
T. Seki, M. Tsujikawa, K. Ito +4
A perpendicularly magnetized ferromagnetic layer is an important building block for recent/future highdensity spintronic memory applications. This paper reports on the fabrication…
Machine learning analysis of tunnel magnetoresistance of magnetic tunnel junctions with disordered MgAl2O4
Shenghong Ju, Yoshio Miura, Kaoru Yamamoto +3
Through Bayesian optimization and the least absolute shrinkage and selection operator (LASSO) technique combined with first-principles calculations, we investigated the tunnel magn…
