GeV0 spin system for diamond. Magnetic parameters from Nadolinny et al., Phys. Status Solidi A 213, 2623 (2016), DOI link. The centre is modelled as a spin-1 electron, isotope label E3, with the g-tensor [2.0027 2.0027 2.0025] and an axial zero-field splitting of 80.3 mT, converted into Hz with the free electron magnetogyric ratio, both expressed in the trigonal frame whose z axis is the [111] direction. A germanium nucleus may be added: 73Ge comes with an isotropic hyperfine coupling of 1.64 mT, any other isotope string is added without a hyperfine tensor, and 'none' leaves the electron alone. The tensors are rotated by the matrix that aligns the requested crystal plane normal with the magnetic field, and the zero-field splitting is converted into irreducible spherical tensor form with mat2ias.m before it is placed on the diagonal of coupling.matrix.

Syntax

Parameters

    parameters is a structure with the following fields:

      .germanium    - '73Ge', 'none', or another germanium isotope
      .orientation  - '111', '110', or '100' crystal plane normal
                      aligned with the magnetic field
