Filtering and imaging of frequency-degenerate spin waves using nanopositioning of a single-spin sensor
Brecht G. Simon, Samer Kurdi, Joris J. Carmiggelt +3
Nitrogen-vacancy (NV) magnetometry is a new technique for imaging spin waves in magnetic materials. It detects spin waves by their microwave magnetic stray fields, which decay evan…
Broadband microwave detection using electron spins in a hybrid diamond-magnet sensor chip
Joris J. Carmiggelt, Iacopo Bertelli, Roland W. Mulder +6
Quantum sensing has developed into a main branch of quantum science and technology. It aims at measuring physical quantities with high resolution, sensitivity, and dynamic range. E…
Electrical spectroscopy of the spin-wave dispersion and bistability in gallium-doped yttrium iron garnet
Joris J. Carmiggelt, Olaf C. Dreijer, Carsten Dubs +2
Yttrium iron garnet (YIG) is a magnetic insulator with record-low damping, allowing spin-wave transport over macroscopic distances. Doping YIG with gallium ions greatly reduces the…
Directional excitation of a high-density magnon gas using coherently driven spin waves
Brecht G. Simon, Samer Kurdi, Helena La +7
Controlling magnon densities in magnetic materials enables driving spin transport in magnonic devices. We demonstrate the creation of large, out-of-equilibrium magnon densities in…
Exciton-to-trion conversion as a control mechanism for valley polarization in room-temperature monolayer WS
Joris J. Carmiggelt, Michael Borst, Toeno van der Sar
Transition metal dichalcogenide (TMD) monolayers are two-dimensional semiconductors with two valleys in their band structure that can be selectively addressed using circularly pola…
A Magnon Scattering Platform
Tony X. Zhou, Joris J. Carmiggelt, Lisa M. Gächter +9
Scattering experiments have revolutionized our understanding of nature. Examples include the discovery of the nucleus, crystallography, and the discovery of the double helix struct…
Magnetic resonance imaging of spin-wave transport and interference in a magnetic insulator
Iacopo Bertelli, Joris J. Carmiggelt, Tao Yu +6
Spin waves - the elementary excitations of magnetic materials - are prime candidate signal carriers for low dissipation information processing. Being able to image coherent spin-wa…
