摘要: We report on elastic neutron scattering results showing that the intermediate phase of quartz existing in a 1.3 K range between 03B1 and 03B2 phases is fact incommensurate. Six satellites are observed around most Bragg peaks along three [100] directions reciprocal space. The modulation corresponds to superposition sinusoidal plane waves as no higher order harmonics observed. With decreasing temperature vector decreases from 0.033 0.029 units. Premonitory diffuse few degrees above Ti = 847.2 K, incommensurate transition temperature. discussed relation with current theories many respect analogous situation NaNO2.
