| Research Abstract |
I have grown single crystals of alpha type rare-earth sesquisulfides having an orthorhombic crystal structure and clarified that the physical properties of these single crystals occasionally demonstrate steep or gigantic responses to temperature, magnitude or direction of magnetic field and electrical field in low temperatures below about 10 K through the measurements of magnetization, electrical resistivity, Seebeck coefficient and specific heat. I am convinced these phenomena originate from metastable multiple structures in the present matter; therefore, I aimed for control of physical properties via controlling magnetic phase using external fields or environmental factors and consequently succeeded in revealing novel magnetic phase in single crystal of dysprosium sesquisulfide alpha-Dy2S3 by contriving application-procedure of magnetic field.
