The role of magnetic excitations in magnetoresistance and Hall effect of slightly TM-substituted BaFe${}_2$As${}_2$ compounds (TM = Mn, Cu, Ni)

We report on electrical resistivity, magnetoresistance (MR) and Hall effect measurements in four non-superconducting BaFe${}_{2-x}$TM${}_x$As${}_2$ (TM = Mn, Cu and Ni) single crystals w…
