6. m are also induced by higher-order effects of GL expansion. This symmetry property produces finite ferrocomponents of quadrupoles, which contribute energetically to AFQ phase. On the other hand, other moments should remain zero due to the symmetry and cannot contribute to the energy, even if their coupling constants are finite.

8. η. However this replacement does not affect the resulting expression of energy (22). In this connection it is to be noted that φ is a homogeneous variable independent of sites. The mixed quadrupole makes a staggered arrangement on the homogeneously rotated plane (Fig. 2).

10. We do not consider the effect of field-induced multipoles for simplicity. It is expected that the stable phase is not changed from the present result even if other multipolar interactions are included. This is because the effects of field-induced multipoles are cooperative to the quadrupolar model as shown in ref. 2. Of course it is important for the realistic calculation of the field-dependence of various quantities (transition temperature etc.) in the high-field region. It is also noted that this analysis implicitly assumes a paramagnetic AFQ state, and does not consider a complicated coexistence with AFM discussed in ref. 2.
