Anomalous spin–lattice coupling in a 2D antiferromagnetic semiconductor revealed by surface acoustic Rayleigh waves

Abstract Magnetic order in van der Waals magnets can strongly influence their lattice dynamics, yet how it affects local and macroscopic manifestations of spin-phonon coupling remains unclear. Optical phonons probe bond-scale exchange modulation and short-range spin correlations,...

High-Permeability Pulse-Reverse Electroplated NiFe for Integrated Chip-Scale Magnetic Shielding in Cryogenic Quantum Systems

Abstract Compact passive magnetic shielding at the chip and package level is essential for cryogenic quantum and superconducting systems, where even weak static magnetic fields can degrade device performance. In this work, a pulse-reverse electroplating strategy for NiFe (80:20)...
