  abstract = {We investigate, experimentally and theoretically, the epitaxy of body-centered-cubic
	Fe on hexagonal GaN. For growth on the Ga-polar GaN(0001) surface
	we find the well-known Pitsch-Schrader orientation relationship between
	Fe and GaN. On the N-polar GaN(0001̅ ) surface we observe coexistence
	between the familiar Burgers orientation and a new orientation in
	which the Fe(001) plane is parallel to GaN(0001̅ ). This “cube-on-hexagon”
	orientation constitutes the high-symmetry link required for constructing
	a symmetry diagram for bcc/hcp systems in which all orientation relationships
	are connected by simple rotations.},
