We demonstrate pseudo spin valves (PSVs) with a (112)-textured D022 Mn2.3-2.4Ga (MnGa) tilted magnetization fixed layer and an in-plane CoFe free layer. Single D022 MnGa films exhibit a small magnetoresistance (MR) typically observed in metals. In MnGa/Cu/CoFe PSVs, a transition from a negative (-0.08%) to positive (3.88%) MR is realized by introducing a thin spin polarizing CoFe insertion layer at the MnGa/Cu interface and tailoring the MnGa thickness. Finally, the exchange coupling between the MnGa and CoFe insertion layer is studied using a first-order reversal curve technique. © 2010 IEEE.
