Crystal Growth of Ce2Ge2Mg2
POSTER
Abstract
Quantum spin liquids (QSL's) are defined as a phase of matter and a superposition of all possible configurations of spin singlets. It is formed from anti-ferromagnetic spin interactions in a specific medium. Shastry-Sutherland Lattice's (SSL) are anticipated as hosts to QSL's. One way this can be analyzed is through the medium of a crystal material called Ce2Ge2Mg, where the Ce ions sit on an SSL. Over a span of ten weeks, attempts at the growth of Ce2Ge2Mg through the Flux Method has been attempted. The main goal was to achieve a 2:2:1 ratio of Ce, Ge and Mg, respectively. Results demonstrate a failure at receiving the ideal ratio, however, crystal material was successfully acquired. Through the act of adjusting the initial ratios of the three materials, more samples can be made to acquire Ce2Ge2Mg in order to confirm the relationship between the SSL and QSL's.
