Abstract Electric control of magnetization dynamics in two-dimensional (2D) magnetic materials is an essential step for the development of novel spintronic nanodevices. Electrostatic gating has been shown to greatly affect the static magnetic propert

Using optically generated spin–orbit torques induced by the heavy metal Pt, we demonstrate coherent control of GHz ferromagnetic resonances in Pt/Co/Pt multilayers as well as sub-THz exchange resonances in [Gd/Co]2 multilayers. Employing a double-p

Abstract We present a new approach to tuning-fork-based atomic force microscopy for utilizing advanced “tip-on-chip” probes with high sensitivity and broad compatibility. Usually, such chip-like probes with a size reaching 2 × 2 mm2 drastically

Abstract Spin‐orbitronics and single pulse all‐optical switching (AOS) of magnetization are two major successes of the rapidly advancing field of nanomagnetism in recent years, with high potential for enabling novel, fast, and energy‐efficient

Abstract Ultrafast laser‐induced dynamics in a ferrimagnetic gadolinium iron cobalt (Gd/FeCo) multilayer with a magnetization compensation temperature of TM = 320 K is studied at room temperature as a function of laser‐fluence and strength of the

Some magnetic materials can switch magnetization via a single laser pulse. However, while very fast, the mechanism is not deterministic. Here, the authors demonstrate a deterministic method of writing opposite magnetization states optically with a se

Abstract Magnetic domain wall motion could be the key to the next generation of data storage devices, shift registers without mechanically moving parts. Various concepts of such so-called ‘racetrack memories’ have been developed, but they are usu

Design and simulations of an integrated photonic device that can optically detect the magnetization direction of its ultra-thin (∼12 nm) metal cladding, thus ‘reading’ the stored magnetic memory, are presented. The device is an unbalanced Mach

Iron nanostructures grown by focused electron beam induced deposition (FEBID) are promising for applications in magnetic sensing, storage and logic. Such applications require a precise design and determination of the coercive field (HC), which depend

We introduce a hybrid plasmonic-photonic device for on-chip all-optical switching and reading of ferrimagnet bits with perpendicular magnetic anisotropy in a racetrack spintronic memory, coupled onto an indium phosphide waveguide. The device comprise
