Experimental Evidence of t2g Electron-Gas Rashba Interaction Induced by Asymmetric Orbital Hybridization
Ganesh Ji Omar, Weilong Kong, Hariom Jani +11
We report the control of Rashba spin-orbit interaction by tuning asymmetric hybridization between Ti-orbitals at the LaAlO3/SrTiO3 interface. This asymmetric orbital hybridization…
Artificial two-dimensional polar metal by charge transfer to a ferroelectric insulator
W. X. Zhou, H. J. Wu, J. Zhou +20
Integrating multiple properties in a single system is crucial for the continuous developments in electronic devices. However, some physical properties are mutually exclusive in nat…
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…
Tailoring the electronic properties of SrRuO3 films in SrRuO3/LaAlO3 superlattices
Z. Q. Liu, M. Yang, W. M. Lü +10
The electronic properties of SrRuO3/LaAlO3 (SRO/LAO) superlattices with different interlayer thicknesses of SRO layers were studied. As the thickness of SRO layers is reduced, the…
Unexpected Anisotropic Two Dimensional Electron Gas at the LaAlO3/SrTiO3 (110) Interface
A. Annadi, X. Wang, K. Gopinadhan +17
The observation of a two dimensional electron gas (2DEG) (1, 2), superconductivity (3, 4), magnetic effects (5) and electronic phase separation (6-8) at the interfaces of insulatin…
Reversible room-temperature ferromagnetism in Nb-doped SrTiO3 single crystals
Z. Q. Liu, W. M. Lu, S. L. Lim +8
The search for oxide-based room-temperature ferromagnetism has been one of the holy grails in condensed matter physics. Room-temperature ferromagnetism observed in Nb-doped SrTiO3…
Reversible metal-insulator transition in LaAlO3 thin films mediated by intragap defects: An alternative mechanism for resistive switching
Z. Q. Liu, D. P. Leusink, W. M. Lü +13
We report on the electric-field-induced reversible metal-insulator transition (MIT) of the insulating LaAlO3 thin films observed in metal/LaAlO3/Nb-SrTiO3 heterostructures. The swi…
Carrier freeze-out induced metal-insulator transition in oxygen deficient SrTiO3 films
Z. Q. Liu, D. P. Leusink, X. Wang +11
We report the optical, electrical transport, and magnetotransport properties of high quality oxygen deficient SrTiO3 (STO) single crystal film fabricated by pulsed laser deposition…
Nonlinear Insulator in Complex Oxides
Z. Q. Liu, D. P. Leusink, W. M. Lü +10
The insulating state is one of the most basic electronic phases in condensed matter. This state is characterised by an energy gap for electronic excitations that makes an insulator…
