Irreversible magnetization switching using surface acoustic waves

, 2013
An analytical and numerical approach is developped to pinpoint the optimal experimental conditions to irreversibly switch magnetization using surface acoustic waves (SAWs). The layers are magnetized perpendicular to the plane and two switching mechanisms

SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, EarlyView.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

Surface acoustic wave driven ferromagnetic resonance in (Ga,Mn)(As,P) epilayers

, 2014
Interdigitated transducers were used to generate and detect surface acoustic waves on a thin layer of (Ga,Mn)(As,P). The out-of-plane uniaxial magnetic anisotropy of this dilute magnetic semiconductor is very sensitive to the strain of the layer, making ...

Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

Surface and Interface Analysis, Volume 58, Issue 6, Page 387-399, June 2026.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...

Controlling surface acoustic waves (SAWs) via temporally graded metasurfaces

Journal of Sound and Vibration
In this manuscript, the temporal rainbow effect for surface acoustic waves (SAW) is illustrated through a temporal analog of space metagradings. We show that a time-modulated array of mechanical resonators induces a wavenumber-preserving frequency transformation which, in turn, dictates Rayleigh-to-Shear wave conversion. The process is unfolded through
