Abstract
Formation of dark and black spin wave envelope solitons was achieved in a magnetic film waveguide by using as an input signal a sequence of two microwave wave packets with a controlled time delay and phase shift between them. A nonlinear phase shift acquired in the process of dark soliton excitation was detected and measured. Generation of a single black soliton with a 180° phase jump was realized when the excitation-related nonlinear phase shift was compensated for by the adjustment of the relative phase in the sequence of the input wave packets.
