✦ Synopsis

The motion of two magnetic holes in a rotating magnetic field is studied both experimentally and numerically. The transport in the azimuthal direction is anomalous and is shown to be well modelled by a fractal time random walk for which the probability distribution of waiting times r follows a power law r-~ /~ with the exponent fl depending on the field anisotropy.
