Theory and Experiment of Chirality-induced Magnetic Nonreciprocity Manifested by Coupling Phase
Jiguang Yao, Ying Yang, Chenyang Lu +4
Magnetic interactions have long served as the most robust and widely used approach for realizing nonreciprocity, with an externally applied magnetic field breaking time-reversal sy…
Coherent Microwave Emission of a Gain-Driven Polariton
Bimu Yao, Y. S. Gui, J. W. Rao +3
By developing a gain-embedded cavity magnonics platform, we create gain-driven polariton (GDP) that is activated by an amplified electromagnetic field. Distinct effects of gain-dri…
Unconventional Singularity in Anti-Parity-Time Symmetric Cavity Magnonics
Y. Yang, Yi-Pu Wang, J. W. Rao +4
By engineering an anti-parity-time (anti-PT) symmetric cavity magnonics system with precise eigenspace controllability, we observe two different singularities in the same system. O…
Electrical detection of magnon-photon interaction via auxiliary spin wave mode
Peng-Chao Xu, J. W. Rao, Y. Wang +4
We report on the electrical detection of a hybrid magnon-photon system, which is comprised of a magnetic sample coupled to a planar cavity. While the uniform Kittel mode has the la…
Travelling photons mediated interactions between a magnon mode and a cavity photon mode
J. W. Rao, Y. P. Wang, Y. Yang +5
We systematically study the indirect interaction between a magnon mode and a cavity photon mode mediated by travelling photons of a waveguide. From a general Hamiltonian, we derive…
Nonreciprocity and Unidirectional Invisibility in Cavity Magnonics
Yi-Pu Wang, J. W. Rao, Y. Yang +5
We reveal the cooperative effect of coherent and dissipative magnon-photon couplings in an open cavity magnonic system, which leads to nonreciprocity with a considerably large isol…
Coherent control of magnon radiative damping with local photon states
B. M. Yao, T. Yu, Y. S. Gui +4
The collective excitation of ordered spins, known as spin waves or magnons, can in principle radiate by emitting travelling photons to an open system when decaying to the ground st…
Quantifying the complex permittivity and permeability of magnetic nanoparticles
B. M. Yao, Y. S. Gui, M. Worden +7
The complex permittivity and permeability of superparamagnetic iron-oxide nanoparticles has been quantified using a circular waveguide assembly with a static magnetic field to alig…
Spin rectification for collinear and non-collinear magnetization and external magnetic field configurations
Y. Huo, L. H. Bai, P. Hyde +2
Spin rectification in a single crystal Fe/Au/Fe sandwich is electrically detected for collinear and non-collinear magnetization and external magnetic field configurations. The line…
Quantized Dispersion of Two-Dimensional Magnetoplasmons Detected by Photoconductivity Spectroscopy
S. Holland, Ch. Heyn, D. Heitmann +4
We find that the long-wavelength magnetoplasmon, resistively detected by photoconductivity spectroscopy in high-mobility two-dimensional electron systems, deviates from its well-kn…
