Title: Mn-induced Ferromagnetic Semiconducting Behavior with Linear Negative Magnetoresistance in Sr 4(Ru 1-xMn x) 3O 10 Single Crystals

Triple-layered Sr 4Ru 3O 10 is a unique ferromagnet with the central RuO 6 layer behaving differently from two outer layers both crystallographically and magnetically. Here, we report that the partial substitution of Ru by smaller Mn gives rise to modification in crystal structure, electronic and magnetic properties of Sr 4(Ru 1-xMn x) 3O 10. Through the single crystal X-ray diffraction refinement, we find that (Ru/Mn)O 6 octahedral rotation is no longer detectable at x ≥ 0.23, leading to the tetragonal structure. The magnetization measurements indicate the ferromagnetic transition temperature T C decreases from 105 K for x = 0 to 30 K for x = 0.41, with the reduced magnetic moment as well. Remarkably, Mn doping results in the change of magnetic anisotropy from the easy c axis in x = 0 to the easy ab plane seen in x = 0.34 and 0.41. Such change also removes the ab-plane metamagnetic transition observed in x = 0. Furthermore, the electrical resistivity increases with increasing x showing semiconducting behavior with Δ ~ 10 meV for x = 0.34 and 30 meV for x = 0.41. Under applied magnetic field, the magnetoresistance exhibits negative and linear field dependence in all currentmore » and field configurations. These results clearly indicate Sr 4(Ru 1-xMn x) 3O 10 is a novel ferromagnetic semiconductor with exotic magnetotransport properties.« less
