Nonreciprocal dynamics of ferrimagnetic bimerons

چکیده

Magnetic bimerons are topologically nontrivial spin textures in in-plane easy-axis magnets, which can be used as particle-like information carriers. Here, we report a theoretical study on the nonreciprocal dynamics of asymmetrical ferrimagnetic (FiM) induced by currents. The FiM have ability to move at speed kilometers per second and do not show skyrmion Hall effect angular momentum compensation point. Our micromagnetic simulations analytical results demonstrate that currents able induce transport drift motion bimeron even if system is By analyzing current-induced effective fields, find attributed asymmetry structure. useful for understanding physics ferrimagnets may provide guidelines building bimeron-based spintronic devices.

Nonreciprocal Localization of Photons.

We demonstrate that it is possible to localize photons nonreciprocally in a moving photonic lattice made by spatiotemporally modulating the atomic response, where the dispersion acquires a spectral Doppler shift with respect to the probe direction. A static defect placed in such a moving lattice produces a spatial localization of light in the band gap with a shifting frequency that depends on t...

All-passive nonreciprocal metastructure

One-way propagation of light, analogous to the directional flow of electrons in the presence of electric potential difference, has been an important goal in the wave-matter interaction. Breaking time-reversal symmetry in photonic flows is faced with challenges different from those for electron flows. In recent years several approaches and methods have been offered towards achieving this goal. H...

Nonreciprocal waveguide Bragg gratings.

The use of a complex short-period (Bragg) grating which combines matched periodic modulations of refractive index and loss/gain allows asymmetrical mode coupling within a contra-directional waveguide coupler. Such a complex Bragg grating exhibits a different behavior (e.g. in terms of the reflection and transmission spectra) when probed from opposite ends. More specifically, the grating has a s...

Nonreciprocal magnetic photonic crystals.

We study band dispersion relations omega(k-->) of a photonic crystal with at least one of the constitutive components being a magnetically ordered material. It is shown that by proper spatial arrangement of magnetic and dielectric components one can construct a magnetic photonic crystal with strong spectral asymmetry (nonreciprocity) omega(k-->) not equal omega(-k-->). The spectral asymmetry, i...

Nonreciprocal active metamaterials

We show experimentally that active electromagnetic metamaterials are suitable for the implementation of a large class of nonreciprocal media characterized by magnetoelectric constitutive parameters that cannot be achieved in passive materials. We design, fabricate, and characterize an isolator made of such an active metamaterial slab and show that it is essentially transparent to microwaves pro...
