​The year 2014 marks the thirtieth anniversary of Sir Michael Berry's ground-breaking work on geometrical phases1, describing how moving particles memorize the paths they are travelling along — much like hikers that remember a travelled landscape. This idea is offering new insight into spin–orbitronics, the art of manipulating spins using spin–orbit coupling. Now, as they report in Nature Nanotechnology, Hidekazu Kurebayashi and colleagues2 have demonstrated that the Berry phase — or more precisely, the Berry curvature — can give rise to a spin–orbit torque that counteracts the damping of magnetization dynamics in systems with broken inversion symmetry.​
