Query: Strain-based Spin Manipulation on Substitutional Nickel in Silicon
  Carbide   By using the full potential linear augmented plane wave (FP-LAPW) method and
full potential local orbital minimum basis (FP-LOMB) method within generalized
gradient approximation (GGA), we studied the electronic structures and magnetic
properties of nickel and chromium single dopants in polytypes of silicon
carbide (SiC). The magnetic phases of defects are found to be strongly
dependent on the external stress on the supercell. In 3C-SiC, the Ni single
dopant exhibits an anti-ferromagnetic (AFM) to ferromagnetic (FM) transition at
a moderate compressive and tensile hydrostatic strain in Si-sub and C-sub
cases. In contrast, the Ni single dopant in 4H-SiC is stably in the nonmagnetic
phase under external stress. The Cr single dopant is also insensitive to the
applied stress but stably in the magnetic phase. This strain controlled
magnetic transition makes the Ni single dopant a novel scheme of qubit.
