This is the open data deposit for data associated with the publication "Phase domain boundary motion and memristance in gradient-doped FeRh nanopillars induced by spin injection" by Temple et al., DOI 10.1063/5.0038950. In addition to this one, it consists of four files: d7_LHS_b3_t75_016.tif - the raw SEM image in figure 1b TEM raw data.zip - the raw TEM data for figure 1c d6_LHS_b3.zip - transport data for a 300 nm device for figures 2 and 3 d7_LHS_b5.zip - transport data for a 500 nm device for figure 4
