Article Synopsis
- High-latitude surface energy budgets (SEBs) are important for understanding land-climate interactions in the Arctic, but uncertainties in their predictions remain.
- A study analyzed SEB observations from 1994 to 2021 and found that vegetation type is a key predictor of SEB components during Arctic summers, often matching or exceeding differences seen between vegetation and glacier surfaces.
- The study also revealed that the timing of SEB fluxes varies significantly with vegetation type, affecting snow-cover dynamics and suggesting that better representations of Arctic vegetation in models could enhance future Earth system predictions.
Strain-Tuned Spin-Wave Interference in Micro- and Nanoscale Magnonic Interferometers.
Nanomaterials (Basel)
April 2022
Here, we report on the experimental study of spin-wave propagation and interaction in the double-branched Mach-Zehnder interferometer (MZI) scheme. We show that the use of a piezoelectric plate (PP) with separated electrodes connected to each branch of the MZI leads to the tunable interference of the spin-wave signal at the output section. Using a finite element method, we carry out a physical investigation of the mechanisms of the impact of distributed deformations on the magnetic properties of YIG film.
