We have optimized the growth of KTiOPO4 (KTP) crystals by a modified Czochralski technique. It has been shown that, as the crystal–melt interface shifts to a larger depth owing to more effective forced melt convection, the optical homogeneity of th

Reorientations of Fe3+ spins have been studied in TbFeO3 single-crystal absorbers by Mossbauer spectroscopy. At low temperature we observed two closely spaced changes of direction of the Fe3+ spins. Below 6.5 K the spins moved from the a towards the
