Intrinsic Spin Photogalvanic Effect in Nonmagnetic Insulator
Ruixiang Fei, Xiaobo Lu, Li Yang
We show that with the help of spin-orbit coupling, nonlinear light-matter interactions can efficiently couple with spin and valley degrees of freedom. This revealed spin photogalva…
Nonreciprocal Second-Harmonic Generation in Few-Layer Chromium Triiodide
Wenshen Song, Ruixiang Fei, Li Yang
It is of fundamental importance but challenging to simultaneously identify atomic and magnetic configurations of two-dimensional van der Waals materials. In this work, we show that…
Giant linearly-polarized photogalvanic effect and second harmonic generation in two-dimensional axion insulators
Ruixiang Fei, Wenshen Song, Li Yang
The second-order nonlinear optical (NLO) processes, such as the photogalvanic effect and second-order harmonic generation (SHG), play crucial roles in probing and controlling light…
Artificial Multiferroics and Enhanced Magnetoelectric Effect in van der Waals Heterostructures
Yan Lu, Ruixiang Fei, Xiaobo Lu +3
Multiferroic materials with coupled ferroelectric and ferromagnetic properties are important for multifunctional devices due to their potential ability of controlling magnetism via…
Meron-Like Topological Spin Defects in Monolayer CrCl3
Xiaobo Lu, Ruixiang Fei, Linghan Zhu +1
Noncollinear spin textures in low-dimensional magnetic systems have been studied for decades because of their extraordinary properties and promising applications derived from the c…
Curie Temperature of Emerging Two-Dimensional Magnetic Structures
Xiaobo Lu, Ruixiang Fei, Li Yang
Recent realizations of intrinsic, long-range magnetic orders in two-dimensional (2D) van der Waals materials have ignited tremendous research interests. In this work, we employ the…
