Ampere–Oersted field splitting of the nonlinear spin-torque vortex oscillator dynamics
Scientific Reports, 2022 We investigate the impact of the DC current-induced Ampère–Oersted field on the dynamics of a vortex based spin-torque nano-oscillator. In this study we compare micromagnetic simulations performed using mumax $$^3$$ 3 and our analytical model based on ...

Generation of Multi-Color Attosecond X-Ray Radiation Through Modulation Compression
, 2011 In this paper, we propose a scheme to generate tunable multi-color attosecond coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modulators, a laser chirper and two bunch compressors ...
