Abstract:
The cubic Heusler alloy Ru2–xMn1+xAl is grown in thin film form on MgO and MgAl2O4 substrates. It is a
highly spin-polarised ferrimagnetic metal, with weak magnetocrystalline anisotropy. Although structurally and
chemically similar to Mn2Ru𝑥Ga, it does not exhibit ferrimagnetic compensation, or large magneto galvanic
effects. The differences are attributed to a combination of atomic order and the hybridisation with the group
13 element Al or Ga. The spin polarisation is around 50% to 60%. There is a gap in the density of states just
above the Fermi level in fully ordered compounds.
