Seeking a Postdoctoral Researcher(W729)

Research field and overview

Strongly correlated electron systems may exhibit various interesting emergent phenomena such as superconductivity, colossal magneto-resistance, and giant magneto-electric effects. These emergent phenomena are directly associated with the spatial distributions as well as the spatial and temporal fluctuations of atoms, electron density, and spin density. We are going to perform crystallographic and magnetic structure analyses, spectroscopies, and microscopies by using synchrotron x-rays, neutrons, and high-energy electron beams to reveal them.

Job title, available positions

Postdoctoral Researcher 1 position
Postdoctoral Researcher is defined as those with a doctoral degree of 5 years or less.

Job description

We are seeking highly motivated condensed-matter scientists in the field of strongly correlated electron systems. The successful candidates will carry out original research relating to one or more of the following research topics by utilizing synchrotron x-rays.

  1. Nontrivial magnetic orders originating from the breaking of space inversion symmetry or the geometrical frustration.
  2. Orbital orders and excitations.
  3. Unconventional electronic states in 5d transition-metal compounds.
  4. Domain structures in ordered states.


Applicants must have a doctor degree (or are expected to have until the employment), and have experience of postdoctoral research of less than 5 years. Previous experience with (i) research of emergent phenomena in strongly correlated electron systems and/or (ii) synchrotron x-ray measurement is desirable.

Work location

Branch and address
RIKEN Wako (2-1 Hirosawa, Wako, Saitama 351-0198)

Salary and benefits

  1. A one-year fixed-term employment contract, renewable based on evaluation, to a maximum 5 years from the initial date of hire.
  2. RIKEN may adjust the above maximum period of renewability based on a) the employee’s abilities, work load at the time of contract completion, performance and work attitude and b) the continuation of the employee’s center, laboratory or project and RIKEN’s management situation and budget at the time. In principle, employment contracts will not be renewed for individuals older than 65 years.
  3. The employee’s period of fixed-term employment cannot exceed 10 years from the initial date of hire (or 10 years from April 1, 2013 for fixed-term employees already at RIKEN prior to this date).
  4. When the center to which the Employee is affiliated is scheduled for a final review in FY2022 and it is decided that the Employee's research will not be continued, the provision given above for projects of limited duration applies and the Employee's contract will not be renewed for the FY2023 year that would extend employment beyond the center's final fiscal year.

The salary system is annual and will be commensurate with qualifications and experience. Commuting and housing allowances will be provided. Social insurance will apply. Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai) is required.
Days off include public holidays, New year’s holidays (Dec. 29 - Jan. 3), and RIKEN Foundation Day.
These and other provisions are in accordance with RIKEN regulations.

*RIKEN promotes a Gender Equity Program by taking various measures to create an equitable workplace where both men and women are able to give full rein to their talents and abilities. When the abilities of candidates are judged to be equivalent through a fair and impartial evaluation process, preference will be given to females.
*Also, eligible for an exemption from repayment for category 1 scholarship loans provided by the Japan Student Services Organization before fiscal year 2003, and eligible for applying for MEXT Grants-in-Aid for Scientific Research (Kakenhi)
