Seeking Postdoctoral Researcher or Research Scientist (W20180)


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

Research Field

The Strong Correlation Materials Research Group aims at studying emergent properties of materials and understanding their mechanisms. We develop new functionality based on the topology of magnetism in strongly-correlated electron materials, such as transition-metal oxides, intermetallic compounds, and layered materials. To this end, we search and synthesize a wide range of compounds using various methods, including CZ, FZ, and high-pressure techniques, and investigate their physical properties and response to external stimuli.

Job title and Job description

Job title, available positions

Postdoctoral Researcher* or Research Scientist** 2 positions

  • * Applicants who received a doctoral degree within the last 5 years
  • ** Applicants who received a doctoral degree 5 or more years ago.

Job description

The successful candidate will explore new magnetic materials that exhibit skyrmions and other topological spin textures, and will investigate their properties, such as magnetic structures and quantum transport phenomena, in close collaboration with Dr. Max Hirschberger (Unit Leader, Topological Quantum Matter Research Unit, RIKEN Center for Emergent Matter Science), following the research plan of “New paradigm of the topological-magnetism science for the beyond-skyrmion era” (PI : Dr. Xiuzhen Yu, Team Leader, Electronic States Microscopy Research Team, RIKEN Center for Emergent Matter Science) in the Research Area of "Creation of Core Technology based on the Topological Materials Science for Innovative Devices" (Research Supervisor: Prof. Masahito Ueda, Univ. of Tokyo), JST CREST


Applicants must have a doctoral degree (or are expected to receive their degree by the time of employment) in condensed matter physics.

  • 5.When the Employee's research is scheduled for review in the Employee's 5 years from the original date of hire at CEMS, and when it is concluded that there is reason* to believe it will be difficult for the research (or technology development) to be continued, the employment contract will not be renewed for the next year. (*The reason may relate to the Employee's abilities, performance and/or work attitude.)

In principle, the first two months of employment is considered a trial period.
Salary will be commensurate with qualifications and experience. Commuting and housing allowances will be provided. Social insurance will be applied. Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai).
