Laue X-ray backscattering of the high-temperature superconductor HgBa2CuO4+δ

Abstract

An attempt is made to grow relatively large (>100 mg) single crystals of the cuprate superconductor HgBa2CuO4+δ. A relatively large sample is seen in the boule of a growth and cut free using a wire saw. This sample is polished and is measured several times with Laue X-ray technique until an image is seen. Eventually, a coherent, four-fold symmetric pattern is seen, but the sample was polished too much and was destroyed in the process.
