Spin waves imaged inside a nano-oscillator launch harder from one edge than the other
A Gothenburg and HZB team filmed magnetization dynamics inside a CoFeB spin Hall nano-oscillator at BESSY II. Simulations matched the movies only after grain boundaries, weakened anisotropy and the Dzyaloshinskii-Moriya interaction were added.
