Single crystalline whiskers of La1-xSrxCuO3-y

Abstract La 1- x Sr x CuO 3- y single crystals in the whiskers-like form were obtained by spontanous crystallization method from the CuO flux. Strontium distribution coefficient has been found to be k = 0.6. It has been shown that the La 1- x Sr x CuO 3- y solid solution region (under equilibrium growth conditions) is spread to x = 0.
