A new synchrotron X-ray diffractometer with a 40 Tesla pulsed field magnet was developed. This instrument observed field-dependent lattice distortion in cobalt oxide (CoO) up to 38 T.

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Instrumentation

Background:

  • High magnetic fields are crucial for studying material properties.
  • Existing equipment may have limitations in field strength or experimental integration.
  • Synchrotron X-ray diffraction provides atomic-level structural information.

Purpose of the Study:

  • To develop and describe a novel synchrotron X-ray diffractometer integrated with a high-field pulsed magnet.
  • To demonstrate the instrument's capability in probing field-induced structural changes.
  • To investigate magnetostriction effects in materials under extreme magnetic fields.

Main Methods:

  • Development of a pulsed field magnet (up to 40 T) with a 3 mm gap for X-ray passage.
  • Utilizing a PILATUS 100K pixel detector for recording X-ray diffraction patterns.
