Special Issue Information

Dear Colleagues,

Light, as an electromagnetic wave, possesses electric, and magnetic field components, along with degrees of freedom such as spin, angular momentum, frequency, phase, polarization, and intensity (thermal effects). These characteristics enable a myriad of physical mechanisms for interactions with both magnetic and optical materials, spanning from high to low dimensions, from macroscopic to nano- and even atomic scales, and across ultrafast timescales, significantly enriching both optics and magnetism. Light can alter magnetic properties, induce magnetism in non-magnetic systems, and control magnetic ordering states, leading to the emergence of diverse technologies and applications.

We are pleased to announce a special issue in the journal Nanomaterials titled “Magnetics Meets Optics: Nanomaterials for Emerging Technologies and Applications”. This Special Issue will delve into the profound interplay between light and magnetism, exploring how electromagnetic waves facilitate a wide range of interactions with diverse magnetic/optical materials, particularly at the micro- and nanoscales. This Special Issue highlights the latest theoretical developments, practical applications, and emerging technologies that are poised to influence and shape the intersection of optics and magnetism.

We welcome contributions on a range of topics, including but not limited to light-induced magnetism, cavity spintronics, magnetoplasmonics, and magneto-optical effects. We encourage studies on angular momentum transfer between light and magnetism, ultrafast magnetization dynamics, magnetic textures, first-principle calculations of optical and magnetic nanomaterials, magnetism-related optical nonlinearity, and optical field manipulation technologies. Further areas of interest include multiferroics, magnetic phase transition, magnetic metamaterials, magnetic resonance, and hybrid quantum systems involving magnetic, optical, and acoustic interactions.

This Special Issue aims to foster collaboration and innovation at the intersection of magnetics and optics, contributing to the advancement of next-generation technologies. We are looking forward to your valuable contributions.

In this work we demonstrate the laser-driven reconfiguration of stripe domains in a thick bismuth-substituted iron garnet film with the (210) crystallographic orientation exhibiting strong in-plane anisotropy. Under a weak in-plane external magnetic field (H), laser irradiation leads to local “twisting” of the magnetic domains; domains with opposite magnetization rotate in different directions. The twisting angle increases linearly with the in-plane magnetic field (H) (above a threshold of approximately 6 Oe) and also changes linearly with the average laser intensity, being fully reversible after the irradiation process. The magnitude of the domain rotation effect does not depend on the light polarization state or its orientation. After optical irradiation, the magnetization distribution in the sample returns to its initial state. It is also observed that moving the focused beam spot along the surface can lead to irreversible modifications in the domain topology in several ways: there is a shift in the dislocations in stripe domain structure (domain “heads”) across the beam transfer direction, expanding the area with a specific magnetization vector orientation, and the stabilization of domain wall positions by their pinning on crystallographic defects. The proposed analytical model based on a local reducing of the effective anisotropy fully describes the rotation type and angle of domains and domain walls, defining their possible trajectories and certain values of the area heating or local anisotropy modulation and the rotation angles. The experimental results and the theoretical model demonstrate a thermal origin of the laser-induced effect in this type of magnetic domain structure. Full article
