Tailoring magnetic order via atomically stacking 3d/5d electrons
Ke Huang, Liang Wu, Maoyu Wang +18
The ability to tune magnetic orders, such as magnetic anisotropy and topological spin texture, is desired in order to achieve high-performance spintronic devices. A recent strategy…
Cationic vacancy induced room-temperature ferromagnetism in transparent conducting anatase Ti_{1-x}Ta_xO_2 (x~0.05) thin films
A. Rusydi, S. Dhar, A. Roy Barman +16
We report room-temperature ferromagnetism in highly conducting transparent anatase Ti1-xTaxO2 (x~0.05) thin films grown by pulsed laser deposition on LaAlO3 substrates. Rutherford…
A study of small impact parameter ion channeling effects in thin crystals
M. Motapothula, M. B. H. Breese
We have recorded channeling patterns produced by 1 to 2 MeV protons aligned with <111> axes in 55 nm thick silicon crystals which exhibit characteristic angular structure for defle…
Bandgap Controlling of the Oxygen-Vacancy-Induced Two-Dimensional Electron Gas in SrTiO3
Z. Q. Liu, W. Lu, S. W. Zeng +16
We report very large bandgap enhancement in SrTiO3 (STO) films (fabricated by pulsed laser deposition below 800 °C), which can be up to 20% greater than the bulk value, depending…
Electron Accumulation and Emergent Magnetism in LaMnO3/SrTiO3 Heterostructures
Zuhuang Chen, Zhanghui Chen, Z. Q. Liu +19
Emergent phenomena at polar-nonpolar oxide interfaces have been studied intensely in pursuit of next-generation oxide electronics and spintronics. Here we report the disentanglemen…
Anomalous current-induced spin torques in ferrimagnets near compensation
Rahul Mishra, Jiawei Yu, Xuepeng Qiu +3
While current-induced spin-orbit torques (SOTs) have been extensively studied in ferromagnets and antiferromagnets, ferrimagnets have been less studied. Here we report the presence…
