Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Chiroptical and Magneto‐Optical Properties of Chiral Copper Phthalocyanine‐Based Thin Films

ChemistryEurope
Chirality, once considered unrelated to magnetism, has recently been recognized to couple with magnetic fields through magneto‐chiral anisotropies (MChAs), such as magneto‐chiral dichroism (MChD).

Physical origin of giant excitonic and magneto-optical responses in two-dimensional ferromagnetic insulators

Nature Communications, 2019
The magneto-optical (MO) effects probe the electronic and magnetic properties of a material, particularly useful for 2D magnets. Here, the authors show that the large optical and MO responses in ferromagnetic monolayer CrI3 arise from strongly bound ...

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

Advanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

Visible-Wavelength Faraday Rotation Properties of FAPbBr₃ Perovskite Single Crystals for Magneto-Optical Devices

Inorganics
Organic–inorganic hybrid perovskites (OIHPs) have been widely used in fields such as solar cells, photodetectors, and light-emitting diodes due to their simple preparation by solution methods and excellent optoelectronic properties.

Co(II) Optical Absorption in Spinels: Infrared and Ligand-Field Spectroscopic Study of the Ionicity of the bond. Magnetic Structure and Co2+→Fe3+MMCT in Ferrites. Correlation with the Magneto-Optical Properties

Active and Passive Electronic Components, 1998
The analysis of the infrared and ligand field spectra of COM2O4 spinels reveals that the ionicity of these compounds varies in the following order aluminate > gallate > ferrite and chromite > rhodite and cobaltite.
