The subject application describes systems and methods that drive magnetization switching through magnonic spin transfer torque. A spin current is provided to a first magnetic layer with a first magnetic state. The spin current facilitates magnetization switching via a magnonic spin transfer torque in a second magnetic layer with a second magnetic state that is separated from the first magnetic layer by an interface. Alternatively, a spin current is provided to a first magnetic domain with a first magnetic state. The spin current facilitates domain wall propagation via a magnonic spin transfer torque. The domain wall is between the first magnetic domain and a second magnetic domain in a second magnetic state.
