Abstract
The crystal structure of Fe1−xCrx(x = 0, 0.2 and 0.4) materials, with and without
exposure to Hydrogen, is investigated using neutron powder diffraction under the applied
external high-pressure. Above a certain applied pressure, PC, a structural phase transition,
from cubic to hexagonal symmetry, is observed, in agreement with previous x-ray diffraction
results. The PC values exhibit an increase with x increase. The possibility for an
evolution of a magnetic structure with pressure, x and Hydrogen exposure, is examined.
Finally, a broadening of the angular profile of the (200) reflection (cubic phase) is identified
and reported.
