The static structure factor S(q) of liquid germanium is determined at 1123K by neutron diffraction techniques in the range from 0.4 to 8.5 AA-1. The structure factor shows a clear low-lying shoulder on the high side of the scattering angle, near the first peak of S(q). These two peaks indicate a dual structure of the germanium melt. The first one characterises the short-range order and the 'irregular' one is associated with a certain degeneracy of the atomic states of the liquid around the imperfections of the structure, which appear as single vacancies.

Electron paramagnetic resonance has been studied in Zn1-xMnxTe over a wide temperature range 20 Kor=0.37 the resonance is detected at higher temperatures. The values of the relaxation time tau and the g-factor are obtained by fitting an expression for the EPR absorption line in the modified Bloch model to the experimental data. The high-temperature linewidth for x
