At T well below the spin-glass transition temperature, the MR becomes positive and exhibits several glassy features, such as history dependence, memory, and hysteresis. These observations are qualitatively similar to the previously reported behavior of the out-of-plane resistance. The results suggest that the memory effects in the MR are related to the onset of glassiness in the dynamics of doped holes.||URI:||https://hdl.handle.net/10356/99255
