Heat reveals hidden magnetic secrets

Our recent research article on “Distinguishing antiferromagnetic spin sub lattices via the spin Seebeck effect” was featured by Physical Review B as an “Editor’s Suggestion”.  This article discusses how electric voltages generated by temperature gradients across an antiferromagnetic Cr2O3 film enable to get detailed insights into the spin structure of this film.  This provides a new, easy-to-implement method for resolving changes of the magnetic structures of antiferromagnets.

Resonant Dynamics of Magnetic Whirls in the Spotlight

Our recent Perspective article on “Dynamic excitations of chiral magnetic textures” was featured by APL Materials as an “Editor’s Pick”.  This perspective article discusses the different type of dynamic magnetic excitations that occur in chiral magnetic materials with a specific focus on skyrmions.  In particular we also discuss what the experimental hurdles are to observe them, and how these excitations may inform new applications, such as information technologies.

Perspective on Hybrid Magnonics Featured by AIP Publishing

Our recent Perspective article on “Hybrid magnonics: Physics, circuits, and applications for coherent information processing” was featured by the Journal of Applied Physics.  This perspective article focuses on the fundamental physics and device application of hybrid magnon modes, particularly with their potential for coherent information processing.  This build on the recent rapid developments of magnon-based hybrid systems, which seek to combine magnonic excitations with diverse excitations for transformative applications in devices, circuits, and information processing. Key to their promising potentials is that magnons are highly tunable excitations and can be easily engineered to couple with various dynamic media and platforms.
