Growth and characterization of large CeAlO sub(3) perovskite crystals

This study is focused on obtaining large CeAlO sub(3) single crystals. Using Czochralski and Edge-Defined Film Fed Growth techniques, crystals of length up to 130 mm were obtained. The crystals belong to the tetragonal low temperature modification of CeAlO sub(3), space group P4/mmm, a=3.7669 Aa, с...

Description
Summary:This study is focused on obtaining large CeAlO sub(3) single crystals. Using Czochralski and Edge-Defined Film Fed Growth techniques, crystals of length up to 130 mm were obtained. The crystals belong to the tetragonal low temperature modification of CeAlO sub(3), space group P4/mmm, a=3.7669 Aa, с =3.7967 Aa. Density and crystallographic parameters as well as some optical, luminescence and magnetic properties of CeAlO sub(3) were studied. The crystals demonstrate rather bright luminescence under UV-excitation, while no luminescence has been registered under X-rays. Ceramic and single crystalline CeAlO sub(3) samples demonstrate p-type conductivity and promising paramagnetic properties.
