We use electrical detection, in combination with microwave transmission, to investigate both resonant and nonresonant magnon-photon coupling at room temperature. Spin pumping a dynamically coupled system is found be distinctly different from previous experiments. Characteristic features such as modes anticrossing, linewidth evolution, peculiar line shape, resonance broadening are systematically measured consistently analyzed by theoretical model set on the foundation of classical...

We report dissipative magnon-photon coupling caused by cavity Lenz effect, where the magnons in a magnet induce rf current cavity, leading to back action that impedes magnetization dynamics. This effect is revealed our experiment as level attraction with coalescence of hybridized modes, which distinctly different from repulsion mode anticrossing coherent coupling. develop method control in- terpolation and coupling, observe matching condition two effects cancel. Our work sheds light on...

This work reviews and examines two particular issues related with the new technique of electrical detection ferromagnetic resonance (FMR). powerful has been broadly applied for studying magnetization spin dynamics over past ten years. The first issue is relation distinction between different mechanisms that give rise to a photovoltage via FMR in spintronic devices, second proper analysis line shape, which become ``Achilles heel'' interpreting experimental results, especially either pumping...

Using electrical detection of a strongly coupled spin-photon system comprised microwave cavity mode and two magnetic samples, we demonstrate the long distance manipulation spin currents. This distant control is not limited by diffusion length, instead depending on interplay between local global properties system, enabling systematic current over large scales (several centimeters in this work). flexibility opens door to improved generation for spintronic devices.

This paper presents the operational difference technique for generating, augmenting, and minimizing test suites. The is analogous to structural code coverage techniques, but it operates in semantic domain of program properties rather than syntactic text. automatically selects cases; assumes only existence a source cases. dynamically generates abstractions (which describe observed behavior are syntactically identical formal specifications)from suite executions. Test suites can be generated by...

We experimentally examine the topological nature of a strongly coupled spin-photon system induced by damping. The presence both spin and photonic losses results in non-Hermitian with variety exotic phenomena dictated structure eigenvalue spectra an exceptional point (EP), where eigenvectors coalesce. By controlling resonance frequency coupling strength we observe crossing for cooperativities above one, suggesting that boundary between weak strong should be based on EP location rather than...
