Abstract

We present experimental proof that in rotating B3 the vortex-core transition temperature TV separates axisymmetric vortices above TV from vortices with spontaneously broken axial symmetry below TV. The nonaxisymmetry is observed in the presence of coherent spin precession as a new soft Goldstone mode, manifested as oscillations and spiral twisting of the core anisotropy axis. These are driven by the precessing spin via spin-orbit coupling and lead to magnetic relaxation from viscous losses, which depend on vortex pinning.
