Argonne/ISIS Postdoctoral position

[Worlton, Thomas]

ARGONNE NATIONAL LABORATORY/ISIS NEUTRON FACILITY
POSTDOCTORAL POSITION

The Materials Science Division at Argonne National Laboratory is seeking
candidates for a postdoctoral research associate position in neutron
diffraction.  The successful candidate will be located predominantly at the
ISIS pulsed neutron facility at the Rutherford Appleton Laboratory in the
UK.  The research involves using the new high-intensity powder
diffractometer GEM and other state-of-the-art facilities at ISIS to study
the structural and magnetic phase diagrams of materials displaying subtle
transitions driven by parameters such as composition, temperature, magnetic
field and pressure.  With the advent of GEM, it has become possible for the
first time to obtain high-precision structural parameters, often comparable
to those from single crystals, with a few minutes' data acquisitions.
Therefore, multi-dimensional phase diagrams can be constructed using
internal structural parameters, such as anisotropic Debye-Waller factors.
Because of the absolute accuracy of these parameters, close comparisons with
lattice dynamics models are also possible.  Areas of science that will be
the focus of this work include existing and new research programs at both
ISIS and Argonne, namely: magnetoresistive materials, including both
perovskite and layered compounds, magnetoelastic materials, ferroelectric
materials, ionic conductors including battery and fuel-cell materials and
ceramic membranes.  Candidates must have a Ph.D. in Physics, Chemistry,
Materials Science or related subject.  Experience in neutron scattering or
diffraction and computer analysis/programming is preferred.  Postdoctoral
appointees at Argonne much have received their Ph.D. within the last three
years.  The deadline for applications is July 10, 2001 or until the position
is filled.  Please send applications, including a resume and publication
list to Dr. James D. Jorgensen, Materials Science Division, Argonne National
Laboratory, Argonne, IL 60439 (JJorgensen at anl.gov). Further information can
also be obtained from Dr. Jorgensen or Dr. Paolo Radaelli
(p.g.radaelli at rl.ac.uk). Information on GEM can be found on the following

Argonne National Laboratory is an affirmative action/equal opportunity
institution.  Women and minorities are especially encouraged to apply.
