Magnetoelastic coupling in stripe-domain states of yttrium iron garnet

Nimisha Arora, Daniel Prestwood, Takashi Kikkawa +4

We study magnetoelastic coupling in stripe-domain magnetic states of -thick YIG thin films grown on a GGG substrate. Broadband ferromagnetic resonance reveals low-f…

Electronic manipulation of polar order in electron crystal

Takashi Kikkawa, Ziyan Chen, Yuto Fujimoto +8

When interaction among atoms or ions is strong enough, they often arrange periodically, forming a crystal. The arrangement patterns of atoms or ions can encode information, a conce…

All optical excitation of spin polarization in d-wave altermagnets

Marius Weber, Stephan Wust, Luca Haag +14

The recently discovered altermagnets exhibit collinear magnetic order with zero net magnetization but with unconventional spin-polarized d/g/i-wave band structures, expanding the k…

Giant orbital magnetoresistance in the antiferromagnet CoO driven by dynamic orbital angular momentum interaction

Christin Schmitt, Sachin Krishnia, Edgar Galindez-Ruales +12

Recent predictions of orders of magnitude larger orbital current effects compared to spin currents have attracted significant interest. However, the full potential of giant orbital…

Observing Differential Spin Currents by Resonant Inelastic X-ray Scattering

Yanhong Gu, Joseph Barker, Jiemin Li +12

Controlling spin currents, i.e., the flow of spin angular momentum, in small magnetic devices is the principal objective of spin electronics, a main contender for future energy eff…

Spin wave resonance in yttrium iron garnet stripe domains

Daniel Prestwood, Chris E. A. Barker, Kilian D. Stenning +15

We study a thin film yttrium iron garnet sample that exhibits magnetic stripe domains due to a small perpendicular magnetic anisotropy. Using wide-field magneto-optic Kerr effect m…
