Self-organized formation of step-terrace structure in SrRuO3 thin films grown on mixed-terminated SrTiO3 (100) substrates

Ryotaro Arakawa, Sachio Komori, Kotaro Tomita +3

Surface morphology of the substrate and bottom layers plays a critical role in the epitaxial growth of oxide thin films. Here, we report on the self-organized formation of a step-t…

Strain-induced magnetic damping anomaly in LaSrMnO (-) thin films

Ryotaro Arakawa, Sachio Komori, Tomoyasu Taniyama

Magnetic properties of LaSrMnO (LSMO) are highly sensitive to various factors such as the Sr doping level , lattice strain, and oxygen stoichiometry due to the…

Electric field enhancement of the superconducting spin-valve effect via strain-transfer across a ferromagnetic/ferroelectric interface

Tomohiro Kikuta, Sachio Komori, Keiichiro Imura +1

In a ferromagnet/superconductor/ferromagnet (F/S/F) superconducting spin-valve (SSV), a change of the magnetization alignment of the two F layers modulates the critical temperature…
