Original Kurzfassung:
Employing ab initio electronic structure calculations, we study a new class of magnetic
Heusler compounds, which consist only of 3d transition metal atoms, namely, Fe2CrZ and
Co2CrZ, where Z is an early 3d-metal, such as Sc, Ti or V. Although these compounds show
a pseudogap and high spin polarization at the Fermi level, the so-called Slater?Pauling rule is
not applicable to them. Co2CrTi and Co2CrV compounds present robust magnetic properties
due to the short range magnetic exchange interactions and, thus, relatively high values of
Curie temperature far above the room temperature. Moreover, these two compounds keep their
magnetic properties upon B2 disorder that makes them very promising materials for spintronic
and magnetoelectronic applications.
