We explain how a ferromagnetic skyrmion can appear massive in some experiments and massless in others. The answer depends on the nature of the driving force. Two illuminating cases are the Zeeman coupling to a nonuniform magnetic field and the adiabatic spin-transfer torque from an electric current.
Spin orientation by electric current in (110) quantum wells
Nonadiabatic corrections to electric current in molecular junction due to nuclear motion at the molecule-electrode interfaces
All optical quantum control of a spin-quantum state and ultrafast transduction into an electric current
