Stabilization of Ferroelectric Hf0.5Zr0.5O2 Epitaxial Films via Monolayer Reconstruction Driven by Interfacial Redox Reaction
Yufan Shen, Mitsutaka Haruta, I-Ching Lin +3
The binary fluorite oxide Hf0.5Zr0.5O2 tends to grab a significant amount of notice due to the distinct and superior ferroelectricity found in its metastable phase. Stabilizing the…
Field-free superconducting diode effect in noncentrosymmetric superconductor/ferromagnet multilayers
Hideki Narita, Jun Ishizuka, Ryo Kawarazaki +8
The diode effect is fundamental to electronic devices and is widely used in rectifiers and AC-DC converters. At low temperatures, however, conventional semiconductor diodes possess…
Optically-induced magnetization switching in NiCo2O4 thin films using ultrafast lasers
Ryunosuke Takahashi, Takuo Ohkochi, Daisuke Kan +2
Recently, all-optical magnetization control has been garnering considerable attention in realizing next-generation ultrafast magnetic information devices. Here, employing a magneto…
Slow oxidation of magnetite nanoparticles elucidates the limits of the Verwey transition
Taehun Kim, Sangwoo Sim, Sumin Lim +8
Magnetite (Fe3O4) is of fundamental importance as the original magnetic material and also for the Verwey transition near T_V = 125 K, below which a complex lattice distortion and e…
Ultrafast demagnetization in NiCo2O4 thin films probed by time-resolved microscopy
Ryunosuke Takahashi, Yoshiki Tani, Hirotaka Abe +5
Using a time-resolved magneto-optical Kerr effect (TR-MOKE) microscope, we observed ultrafast demagnetization of inverse-spinel-type NiCo2O4 (NCO) epitaxial thin films of the inver…
Spin reorientation in tetragonally distorted spinel oxide NiCoO epitaxial films
Hiroki Koizumi, Ikumi Suzuki, Daisuke Kan +4
We experimentally investigated the magnetic properties of NiCoO epitaxial films known to be conductive oxides with perpendicular magnetic anisotropy (PMA) at room temperatu…
