Analysis of Boron in Holmium Rhodium Borides by Electron Energy Loss Spectroscopy

Abstract

Holmium rhodium borides were analyzed by analytical electron microscopy. In addition to electron diffraction and electron microscopy studies, electron energy loss spectroscopy (EELS) was performed on HoRh3131.333 (nominal composition, B; 25 at%). It was found that HoRh313, 333 consists of two phases, i. e. HoRh3B (B: 20 at%) and HoRh3B2 (B: 33.3at%). These results indicate that EELS of analytical electron microscope is very useful to detect and analize for various boron compounds.
