Abstract
A maximal state of spin polarisation of a spin-1 system with all eight degrees of freedom (namely, three distinct axes and two non-zero scalars) is realised when a spin-1 nucleus with nonzero electric quadrupole moment is embedded in a suitable crystal lattice generating an electric quadrupole field and is exposed to an external constant magnetic field whose direction does not coincide with any of the principal axes characterising the electric quadrupole field. In the absence of the magnetic field only five of the eight degrees of freedom (i.e. two distinct axes and a nonzero scalar) are realised if the asymmetry parameter eta not=0. If eta =0 the two axes coalesce. This suggestion is made to stimulate experimental efforts to produce polarised multiaxial spin-1 targets.
