Ultrafast Ferromagnetic Spin Switching by a Single Pair of Optical Pulses Open
All-optical magnetic recording potentially realizes orders of magnitude faster and more energy-efficient writing of magnetic bits but all-optical switching of ferromagnets is so far ultraslow. Here, we demonstrate a new mechanism to all-op…

Thickness‐Dependent High‐Temperature Piezo‐ and Ferro‐Electricity in a Fluorenone‐Based Molecular Crystal Open
Organic polar crystalline materials, featuring the merits of lightweight, flexibility, and low fabrication costs, are emerging as promising alternatives for inorganic ferroelectrics, but so far, they are not competitive. The main reasons a…

Laser-induced electron dynamics and surface modification in ruthenium thin films Open
We performed the experimental and theoretical study of the heating and damaging of ruthenium thin films induced by femtosecond laser irradiation. Results of an optical pump-probe thermoreflectance experiment with rotating sample allowing t…
Efficient All-Optical Helicity Dependent Switching of Spins in a Pt/Co/Pt Film by a Dual-Pulse Excitation Open
All-optical helicity dependent switching (AO-HDS), deterministic control of magnetization by circularly polarized laser pulses, allows to efficiently manipulate spins without the need of a magnetic field. However, AO-HDS in ferromagnetic m…
Training and pattern recognition by an opto-magnetic neural network Open
Neuromorphic computing aims to mimic the architecture of the human brain to carry out computational tasks that are challenging and much more energy consuming for standard hardware. Despite progress in several fields of physics and engineer…
Nonlinear Optical Properties and Applications of Fluorenone Molecular Materials Open
Fluorenone molecular materials provide an excellent platform to engineer new materials that are very promising for photonic and optoelectronic applications, such as very efficient optical second harmonic (SHG) and terahertz (THz) generatio…
Fully Controllable Structural Phase Transition in Thermomechanical Molecular Crystals with a Very Small Thermal Hysteresis Open
The construction of a practical crystalline molecular machine faces two challenges: to realize a collective molecular movement, and to amplify this movement into a precisely controlled mechanical response in real time and space. Thermosali…
Direct Observation of Incommensurate–Commensurate Transition in Graphene-hBN Heterostructures via Optical Second Harmonic Generation Open
Commensurability effects play a crucial role in the formation of electronic properties of novel layered heterostructures. The interest in these moiré superstructures has increased tremendously since the recent observation of a superconduct…
Nonlinear Optical Perovskites: Halide Perovskites for Nonlinear Optics (Adv. Mater. 3/2020) Open
Halide perovskites are a promising platform for the construction of nonlinear optical materials in light of their structural diversity, high hyperpolarizability, and bandgap tunability. In article number 1806736, Jialiang Xu, Xian-He Bu, a…

Halide perovskites provide an ideal platform for engineering highly promising semiconductor materials for a wide range of applications in optoelectronic devices, such as photovoltaics, light‐emitting diodes, photodetectors, and lasers. Mor…
Efficient all-optical helicity-dependent switching in Pt/Co/Pt with dual laser pulses Open
All-optical helicity-dependent switching (AO-HDS) in ferromagnetic metals so far requires at least 100-1000 laser pulses for fully switching their magnetic states. We demonstrate that using a combination of a short, 90-fs linearly polarize…
All-optical switching of spins in ferromagnetic Co/Pt with a single dual pulse Open
All-optical magnetic recording can achieve breakthroughs in information technologies by merging the advantages of photonics, facilitating the fastest and nearly non-dissipative information transfer, with the unique properties of magnets al…
