Abstract

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.
