A review of natural materials that exhibit negative permittivity or permeability, including
gaseous plasma, metals, superconductors, and ferromagnetic materials, is presented. It is …

A bstract In the presence of axion dark matter, fermion spins experience an “axion wind”
torque and an “axioelectric” force. We investigate new experimental probes of these effects …

Quantum sensors offer unparalleled precision, accuracy, and sensitivity for a variety of
measurement applications. We report a compact magnetometer based on a ferrimagnetic …

We propose a platform that combines the fields of cavity optomagnonics and levitated
optomechanics to control and probe the coupled spin-mechanics of magnetic dielectric …

Accurate measurements of the intrinsic ferromagnetic linewidth of a single-crystal Sc-doped
hexagonal M-type barium ferrite (BaM) 308-µm-diameter sphere at millimeter-wave …

The finite-element method (FEM) is applied for modal analysis of ferrite-loaded spherical
resonators. To improve the efficiency of the numerical calculations, the body-of-revolution …

The electromagnetic (EM) properties of shielded gyromagnetic spheres are characterized
with the aid of an electrodynamic model formulated for the transverse electric (TE) modes of …

This review paper describes the state of the art in measurements of ferromagnetic linewidth,
permeability tensor and saturation magnetization employing electrodynamic theory of …

Progress in fundamental physics requires new experimental data. The point of view of this
thesis is that there are a finite, manageable number of signals that new physics could …

Electron spin resonance (ESR) spectroscopy was used to determine the magnetic state
transitions of nanocrystalline La0. 8 Sr0. 2MnO3 at room temperature, as a function of …
