We propose a scheme to braid Majorana zero modes (MZMs) through steering thespin degree of freedom, without moving, measuring, or more generically fusingthe modes. For a spinful Majorana system, we show that braiding two MZMs isachieved by adiabatically reversing the Majorana spins, which topologicallycorresponds to twisting two associated worldribbons, the extention ofworldlines that track the braiding history of MZMs. We demonstrate thefeasibility of applying the current scheme to thesuperconductor/2D-topological-insulator/ferromagnetic-insulator (SC/2DTI/FI)hybrid system which is currently under construction in experiment. A singlebraiding of two MZMs is precisely achieved by adiabatically reversing the FImagnetization, not relying on details of the reversing path, and the braidingoperation is shown to be stable against local imperfections such as the staticand dynamical disorder effects. The stability is a consequence of the intrinsicconnection of the current scheme to topological charge pumping. The proposeddevice involves no auxiliary MZMs, rendering a minimal scheme for observingnon-Abelian braiding and having advantages with minimized errors for theexperimental demonstration.
