Crystal growth of pyrochlore rare-earth stannates
We report crystal growth of several rare-earth stannates RE 2 Sn 2 O 7 (RE=Pr, Tb, Ho, Dy, Yb and Lu) using the flux technique. Different combinations of flux were tried, and a Na 2 B 4 O 7 -NaF (1.2:1) mixture was found to be suitable for crystal growth. X-ray diffraction and thermal characterisat...

| Summary: | We report crystal growth of several rare-earth stannates RE 2 Sn 2 O 7 (RE=Pr, Tb, Ho, Dy, Yb and Lu) using the flux technique. Different combinations of flux were tried, and a Na 2 B 4 O 7 -NaF (1.2:1) mixture was found to be suitable for crystal growth. X-ray diffraction and thermal characterisation data are presented, as well as some initial measurements of magnetic and thermodynamic properties of the crystals. Little effect was observed with changing oxygen content by Sc substitution for Sn. |
