The MD-SHG spectrum is obtained without tilting the sample ( = 0°) in a magnetic field of 0 H = +50 mT along the [010] axis at T = 12 K in the canted AFM phase. The ED-SHG spectrum is measured...

Apr 16, 2021 · We show that a giant nonreciprocal optical response can occur when transferring from linear to nonlinear optics, specifically second harmonic generation (SHG). CuB 2 O 4 exhibits SHG transmission changes by almost 100% upon reversal of a magnetic field of just ±10 mT.

Sep 22, 2021 · Here, we demonstrate the significant enhancement of SHG and THG in a transition-metal-dichalcogenide (TMDC) MoS 2 metasurface in the sub-diffractive, single-beam nonlinear emission in the visible...

Aug 30, 2024 · Using van der Waals antiferromagnet MnPS 3 as a proof of concept, we demonstrate the tuning of nonreciprocity-induced domain contrast in SHG through applying an in-plane electric field that...

May 8, 2024 · SHG可分为晶格贡献（crystal SHG）和磁结构贡献（MSHG）, 两者在磁矩反转下干涉相长或干涉相消，可以产生丰富的非线性磁光（NLMO）效应（如图1所示）。 但是，长期以来实验上观测到的NLMO效应微弱，严重阻碍了其应用和发展。

Jul 31, 2019 · Our results indicate that SHG is a highly sensitive probe of subtle magnetic orders and open up possibilities for the use of two-dimensional magnets in nonlinear and nonreciprocal optical devices.

Jan 1, 2013 · Spectroscopic studies of magnetically ordered materials, multiferroic insulators, and magnetic semiconductors reveal several previously unexplored mechanisms of optical second harmonic generation (SHG). In contrast to non-magnetic materials, SHG in such systems is determined by arrangements of both charges and spins.

Jan 1, 2005 · Magnetic SHG is introduced as a probe for magnetic structures and sublattice interactions. The specific degrees of optical experiments-including spectral, spatial, and temporal...
