“…The dielectric tensor of MnAs for a 1.5 mm wavelength was needed in this calculation, but no available data had been reported; only the tensor for the visible wavelength range had been reported. 18) Therefore, we measured the values of the tensor elements. The diagonal element of the tensor can be determined from the complex refractive index, and the off-diagonal element can be determined from the Faraday rotation and the Faraday ellipticity.…”

Inflation symmetry is one of the peculiar features of the diffraction pattern of a quasicrystal. However, it is not an exclusive property of quasicrystalline structures and it may be present in incommensurately modulated structures, as shown recently in the Al-Mg system (Donnadieu P et al 1996 J. Physique I 6 1153-64). The conditions that a single modulation parameter of an incommensurate structure must fulfil in order to have inflation symmetry are determined. Although the number of possible distinct inflation-symmetric quasilattices is infinite, from physical/experimental arguments it can be concluded that, in practice, only a few of them can be experimentally observed, the reported phase of the Al-Mg system being one of these particular cases. A quantitative criterion to classify the modulation parameters that give rise to quasilattices with observable inflation symmetry is proposed. The generalization of the analysis of incommensurate structures with more than one single modulation parameter is also discussed. Finally, the inflation parameters of diffraction patterns with rotational point groups of finite order, C N , are compared with the parameters of the one-dimensional case.
