Abstract
Sc(0,1,2,3 mol%): Ce: Fe: LiNbO3 crystals were grown by conventional Czochralski method. The X-ray diffraction is used to determine lattice constants and analyze the internal structure of crystals. The lattice size was found to increase first and then decrease, and the doping elements do not alter the crystal structure. The concentrations of Sc3+, Ce4+, and Fe3+ ions in the crystals were measured using ICP-AES. With the increase of Sc3+ concentration in the melt, the effective segregation coefficient of Sc3+ was found to decrease, while the effective segregation coefficient of Ce4+ and Fe3+ increased. The birefringence gradient of the ScCeFe-3 sample measured using the birefringence gradient method was 3.3 × 10−5 ∆R/cm−1, which was the best optical homogeneity.
期刊介绍：
The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
