Deliberate control of magnon transportation will lead to an energy-efficient technology for information transmission and processing. Y 3 Fe 5 O 12 (YIG), exhibiting extremely large magnon diffusion length due to the low magnetic damping constant, has been intensively investigated for decades. While most of the previous works focused on the determination of magnon diffusion length by various techniques, herein we demonstrated how to tune magnon diffusion by light excitation. We found that the…

Direct excitation of the magnetisation in photon-magnon hybrid systems with an infrared laser pulse

We present experimental results concerning the direct excitation of the magnetisation in a photon-magnon hybrid system composed of a microwave cavity and an embedded yttrium iron garnet (YIG) sphere.

Magnon-driven dynamics of a hybrid system excited with ultrafast optical pulses

The potential of photon-magnon hybrid systems as building blocks for quantum information science has been widely demonstrated, and it is still the focus of much research. We leverage the strengths of

On the: Theory of Superexchange Interaction

The superexchange interaction for the spin coupling in certain magnetic compounds is treated on the basis of an approach which takes into account the deformation of the electron orbitals of the

Photo-spin-voltaic effect

The photo-voltaic effect typically occurs in semiconductors and involves photon-driven excitation of electrons from a valence band to a conduction band. In a region such as a p–n junction that has a

Observation of longitudinal spin-Seebeck effect in magnetic insulators

We propose a longitudinal spin-Seebeck effect (SSE), in which a magnon-induced spin current is injected parallel to a temperature gradient from a ferromagnet into an attached paramagnetic metal. The

Antiferromagnetism. Theory of Superexchange Interaction

In this paper the general formalism of Kramers indicating the existence of superexchange interaction has been reduced, under simplifying assumptions, to the point where actual formulas for the

Optical properties of epitaxial iron garnet thin films

Optical absorption, derivative absorption, reflectivity, and derivative reflectivity data are presented for several iron garnet thin-film compositions grown by liquid-phase epitaxy. In the case of

Ferromagnetic Relaxation. I. Theory of the Relaxation of the Uniform Precession and the Degenerate Spectrum in Insulators at Low Temperatures

A scheme is proposed for the relaxation processes at low temperatures accompanying excitation of uniform precession spin waves in a ferromagnetic resonance experiment, with particular reference to
