“…342,344 The direction of spin polarization is determined by the chirality, resulting in a change of local magnetization at the 2D-chiral-HMH/ferromagnet interface. 358 Figure 16(d) shows the successful observation of light-driven CISS-induced magnetism in the 2D-chiral-HMH/NiFe bilayer detected by Sagnac MOKE. The sample was illuminated at a low laser intensity (≈ 0.5 mW ) to suppress the laser-induced heating.…”

“…Whereas there is no similar change found in the A-chiral-HMH sample, the R-chiral-HMH sample exhibits a surprising increase of the Kerr signal under the same illumination. By reversing the magnetic field, the sign of ∆θ Kerr is inverted depending on the chirality, 358 mimicking the nature of magnetization in typical ferromagnets.…”

Quantum technology has made tremendous strides over the past two decades with remarkable advances in materials engineering, circuit design and dynamic operation. In particular, the integration of different quantum modules has benefited from hybrid quantum systems, which provide an important pathway for harnessing the different natural advantages of complementary quantum systems and for engineering new functionalities. This review focuses on the current frontiers with respect to utilizing magnetic excitatons or magnons for novel quantum functionality. Magnons are the fundamental excitations of magnetically ordered solid-state materials and provide great tunability and flexibility for interacting with various quantum modules for integration in diverse quantum systems. The concomitant rich variety of physics and material selections enable exploration of novel quantum phenomena in materials science and engineering. In addition, the relative ease of generating strong coupling and forming hybrid dynamic systems with other excitations makes hybrid magnonics a unique platform for quantum engineering. We start our discussion with circuit-based hybrid magnonic systems, which are coupled with microwave photons and acoustic phonons. Subsequently, we are focusing on the recent progress of magnon-magnon coupling within confined magnetic systems. Next we highlight new opportunities for understanding the interactions between magnons and nitrogen-vacancy centers for quantum sensing and implementing quantum interconnects. Lastly, we focus on the spin excitations and magnon spectra of novel quantum materials investigated with advanced optical characterization.

Spin-dependent charge transport, along with the potential electronic applications, is investigated in chiral 2D iodide hybrid organic/inorganic perovskites (HOIPs) via the chirality-induced spin selectivity (CISS) effect, paving a new way in spintronics. Despite the high spin-polarized current enhancement, the intrinsic oxidation tendency of iodide ions brings about severe problems in the stability and lifetime of electronic devices. Here, spin-dependent charge transport properties in lead-bromide perovskites hybrid with chiral R/S-methylbenzylammonium (MBA), that is, (R/S-MBA)PbBr 3 are explored. Distinct from layered 2D iodide perovskites (R/S-MBA) 2 PbI 4 which experience obvious crystal degradation along time, (R/S-MBA)PbBr 3 maintain good crystallinity even in the oxidative, humid, and high-temperature environment due to the lower Fermi level of bromide than iodide. Magnetic conductive atomic force microscopy displays a spin filtration efficiency as high as 90%, showing negligible decay after 1 month. This work expands the spin transport to chiral bromide perovskites with higher stability, and thus provides significant support for the practical application of HOIPs in spintronics.

The spin degree of freedom in hybrid organic–inorganic perovskites (HOIPs) has become a rapidly growing research topic in both HOIPs and spintronics fields due to its fundamental scientific significance and tight relevance with optoelectronics. The flourishing achievements of HOIP spintronics call for a timely review to summarize the key progress and guide future developments. In this review, classical spintronic phenomena based on spin‐orbit coupling (SOC) are discussed, especially Rashba splitting and related applications such as spin‐charge conversion. Owing to the unique chirality‐spin coupling, spintronics in chiral HOIPs are particularly focused on, including chirality‐induced spin selectivity (CISS). Based on the complex band structure and carrier/exciton, spin dynamics is also widely investigated and constitutes an indispensable part of HOIP spintronics. Aside from the three main threads, other spintronic phenomena such as magneto‐optical coupling and device exploration are involved as promising opportunities. Despite the continuous breakthroughs in HOIP spintronics, more efforts are required to expand material systems, explore new physics, and optimize device configurations for enhanced performance and high integration. A deep understanding of spin behaviors in HOIPs will create a new platform beyond conventional optoelectronic and photovoltaic applications.
