Optically induced metallic state with persistent monoclinic symmetry in NdNiO
Christian Tzschaschel, Felix Utsch, Qi Song +6
Understanding whether electronic and structural order remain coupled under nonequilibrium conditions is a central challenge in correlated materials. Here, we simultaneously track m…
Ultrafast X-ray sonography reveals the spatial heterogeneity of the laser-induced magneto-structural phase transition in FeRh
Maximilian Mattern, Angel Rodriguez-Fernandez, Roman Shayduk +13
Phase transitions are governed by both intrinsic and extrinsic heterogeneities, yet capturing their spatio-temporal dynamics remains a challenge. While ultrafast techniques track p…
Tunable magnons in a dual-gated 2D antiferromagnet
Nele Stetzuhn, Abhijeet M. Kumar, Sviatoslav Kovalchuk +12
The layered antiferromagnet CrSBr features magnons coupled to other quasiparticles, including excitons and polaritons, enabling their easy optical accessibility. In this work, we i…
X-ray View of Light-Induced Spin Reorientation in TmFeO: Direct Observation of a 90 Néel Vector Rotation
Somnath Jana, Ronny Knut, Dima Afanasiev +8
Using time-resolved X-ray magnetic linear dichroism in reflection, we provide a direct probe of the Néel vector dynamics in TmFeO on a ultrafast timescale. Our measurements rev…
Soft-X-ray momentum microscopy of nonlinear magnon interactions below 100-nm wavelength
Steffen Wittrock, Christopher Klose, Salvatore Perna +10
Magnons are quantised collective excitations of long-range ordered spins. At nanometre wavelengths, exchange interactions increasingly govern their dynamics, giving rise to a large…
Fluence dependent delay of Ni in an FeNi alloy supports an exchange based origin
Somnath Jana, Ronny Knut, Puloma Singh +9
The delayed demagnetization in Ni relative to Fe in the ultrafast demagnetization studies in FeNi alloy has led to two competing theoretical explanations: The Inhomogeneous Magnon…
