| 研究実績の概要 |
According to my research plan, the first six month will mainly focus on the high-quality single crystal growth. After I received the JSPS fellowship, I started to explore the single crystal growth for Mn3X (X = Sn, Ge, Ga) system. Currently, high quality and enough size samples are already obtained. Various properties are checked carefully, which can help us pick out the best samples. These samples make the next measurement feasible.
For this project, another main goal is to get the composition controllable samples. For Mn3Sn system, the composition controllable samples have been successfully grown using Bridgman method in our lab. However, for Mn3Ge system, the Bridgman method does not work. I am trying find out the effective method to control the composition for Mn3Ge and Mn3Ga.

2: おおむね順調に進展している
理由
Currently, high quality samples have already been obtained by flux method. Therefore, I can start the magnetostriction measurement and meanwhile I will continue to grow variant-composition compounds. For Mn3+XGe, I would try to control x change from -0.1 to +0.1. The x value not only affect the magnetic properties, but also influence the transport properties greatly.
