High-temperature structural phase transition in multiferroic LiCu_2O_2

S. A. Ivanov, A. A. Bush, K. E. Kamentsev +4

LiCu_2O_2 single crystals were studied in the temperature range 300-1100 K by means of heating-cooling curves of differential thermal analysis (DTA), thermogravimetry (TG), X-ray p…
