Abstract

In the paper the results of experiments on single crystal growth of CaNdAlO₄ (CNA) are reported. CaNdAlO₄ is a very promising material for use as a substrate for high temperature superconducting (HTSC) epitaxial layers. The method of preparation of charge material as well as the conditions of single crystal growth by the Czochralski method are given. The equipment type MSR-2 with induction heating made by Metals Research Ltd., England and the thermal system with iridium crucible and afterheater were used. The quality of obtained single crystals was examined by polarizing methods. Optical transmission in the range 200 - 2000 nm was also measured. Using a newly developed ESR spin-probing methodology, magnetic properties of this material were investigated. It should be pointed out that because of neodymium presence the material exhibits high paramagnetic susceptibility.
