Researchers Use Soft X-ray Microscopy to Detect Nanometre-Scale Magnons, Advancing Spin Wave Imaging

Researchers have successfully used a new technique called magnon momentum microscopy to directly image magnon populations across two-dimensional momentum space. This method, which employs resonant magnetic soft-X-ray scattering, overcomes previous challenges in detecting magnons at nanometre wavelengths. The technique was applied to yttrium iron garnet, revealing a variety of nonlinear magnon interactions previously unobserved. This advancement allows for the exploration of short-wavelength and nonlinear magnonics, potentially advancing wave-based information processing beyond conventional electronics. The method does not rely on patterned antennas or contacts, offering flexible experimental geometries and capturing interactions over large regions of the dispersion plane.

University of Minnesota Researchers Achieve Atomic Control Over Metal Properties

University of Minnesota Researchers Achieve Atomic Control Over Metal Properties

Researchers at the University of Minnesota Twin Cities have discovered a novel method to manipulate the electronic properties of metals by engineering atomic interactions at the interface of two materials. This breakthrough, published in Nature Communications, involves the use of interfacial polarization to adjust the surface work function of metallic ruthenium dioxide (RuO2) by more than 1 electron volt (eV). The team achieved this by altering the thickness of an ultra-thin film by just a few nanometers. Traditionally, polarization is associated with insulators and ferroelectrics, but the researchers have demonstrated its stabilization within a metallic system, allowing for significant control over electronic behavior. The most notable changes were observed when the ruthenium dioxide film reached a thickness of approximately 4 nanometers, leading to a transition from a strained to a more relaxed atomic arrangement.
