- Abstract
Shear instability of ?-Fe in bulk and in ultrathin film was studied using scanning tunneling microscopy (STM). In the films, the epitaxial constraint limits the shear distortions to narrow domains while shear instability was strongly correlated to the magnetic properties of the films. It is found that along the Bain path describing the transformation of face-centered (fcc) ?-Fe into body-centered-cubic (bcc) ?-Fe, tetragonal Fe is unstable against monoclinic shear deformations producing bcc structure.
