Polarized hyper-Raman scattering study of the silent F2u mode in PbMg1/3Nb2/3O3.
Original language description
A single crystal of the relaxor PbMg1/3Nb2/3O3 is studied by hyper-Raman scattering. The relative scattering intensities obtained for the band near 250?cm-1 in various polarization geometries are fully compatible with hyper-Raman spectroscopy tensor of the F2u zone-center vibrational mode of prototype cubic perovskite structure. The mode was investigated between room temperature and 775 K, thus covering the range around the Burns temperature Td and the crossover temperature.

Studium tichého módu F2u v PbMg1/3Nb2/3O3 pomocí polarizovaného hyper-Ramanova rozptylu
Czech description
Monokrystal of relaxorového ferroelektrika PbMg1/3Nb2/3O3 bul studován pomocí polarizovaného hyper-Ramanova rozptylu. Bylo ověřeno, že relativni rozptylové amplitudy pro fononovy pás u 250 cm-1 jsou kompatibilní s navrženou F2u symetrií této vibrace, bezohledu na polární nanodomény v materiálu. Rozptyl na tomto vibračním módu byl sledován v širokém rozsahu teplot - od pokojové až po 775K.
