Magnetic Domain Wall Networked Films – Configurational Switching for Tunable Magnetization Dynamics by Perforated Thin Films

Advanced Materials Technologies, Volume 9, Issue 7, April 4, 2024.
Deterministic bi‐modal switching of magnetic precession frequencies of magnetic thin films is achieved by manipulating networks of magnetic domain walls through magnetic film perforation. The spatial mechanism is elucidated using dynamic magneto‐optical Kerr microscopy.

GAGA for nonreciprocal emitters: genetic algorithm gradient ascent optimization of compact magnetophotonic crystals

Nanophotonics, Volume 13, Issue 5, Page 773-792, March 2024.
Abstract Fundamental limits of thermal radiation are imposed by Kirchhoff’s law, which assumes the electromagnetic reciprocity of a material or material system. Thus, breaking reciprocity can enable breaking barriers in thermal efficiency engineering.

A Magnetoelastic Twist on Magnetic Noise: The Connection with Intrinsic Nonlinearities

Advanced Functional Materials, Volume 34, Issue 9, February 26, 2024.
Magnetoelastic nonlinearity significantly limits the performance of devices that use ferromagnetic films as sensitive elements. By introducing a comprehensive theory of magnetic noise in sensor systems, previously unrecognized noise sources linked to magnetoelasticity are revealed.

Spatially inhomogeneous inverse Faraday effect provides tunable nonthermal excitation of exchange dominated spin waves

Nanophotonics, Volume 13, Issue 3, Page 299-306, February 2024.
Abstract We demonstrate optical nonthermal excitation of exchange dominated spin waves of different orders in a magnetophotonic crystal. The magnetophotonic structure consists of a thin magnetic film and a Bragg stack of nonmagnetic layers to provide a proper nonuniform interference pattern of the inverse Faraday effect induced by light in the magnetic
