- If \ scriptstyle K _ a > K _ b > 0, the easy axis is the z direction, the intermediate axis is the y direction and the hard axis is the x direction.
- Interestingly, the magnitude of the quantum spin tunnelling splitting can be modulated by application of a magnetic field along the transverse hard axis direction ( in the case of Hamiltonian [ 1 ], with D 0, the x axis ).
