Seeking a Research Scientist or Postdoctoral Researcher (W19211)


Strong Correlation Materials Research Group RIKEN Center for Emergent Matter Science
(Group Director:Yasujiro Taguchi)

Research Field

The Center for Emergent Matter Science (Center Director: Dr. Yoshinori Tokura) is a strategic research center launched on April 1st, 2013. The center aims at constructing a novel condensed matter science and contributing fundamentally toward the realization of an environmentally benign, sustainable society which is recognized as a world-wide problem.

Strong Correlation Materials Research Group aims at obtaining gigantic cross-correlation responses, understanding their mechanisms, and developing new functions in strongly-correlated-electron bulk materials, such as transition-metal oxides. To this end, we try to synthesize a wide range of materials using various methods, including high-pressure techniques, and investigate their physical properties. Specific targets include skyrmion-hosting materials, mutiferroic materials, superconductors, and thermoelectric materials.

Job title and Job description
