      abstract     = {Spintronics applications for high-density non-volatile
                      memories require simultaneous optimization of the
                      perpendicular magnetic anisotropy (PMA) and current-induced
                      magnetization switching. These properties determine,
                      respectively, the thermal stability of a ferromagnetic
                      memory cell and a low operation power consumption, which are
                      mutually incompatible with the spin transfer torque as the
                      driving force for the switching. Here, we demonstrate a
                      strategy of alloy engineering to overcome this obstacle by
                      using electrically induced orbital currents instead of spin
                      currents. A non-equilibrium orbital density generated in
                      paramagnetic γ-FeMn flows into CoPt coupled to the
                      magnetization through spin-orbit interaction, ultimately
                      creating an orbital torque. Controlling the atomic
                      arrangement of Pt and Co by structural phase transition, we
                      show that the propagation length of the transferred angular
                      momentum can be modified concurrently with the PMA strength.
                      We find a strong correlation to the phase transition-induced
                      changes of d orbitals with mₗ = ±1 and mₗ = ±2
                      character. The close link of orbital hybridization to the
                      dynamic orbital response and magnetic properties offers new
                      possibilities to realize optimally designed orbitronics
                      memory and logic applications.This dataset contains the DFT
                      calculations for the electronic structure of CoPt in L1₁
