These authors also misquote ORLICH and HÜFNER regarding the easy direction
of ErIG at low temperatures and report a [ 111 ] easy direction at 1.5 K. Two
nonequivalent sets of Er3 + ion sites are observed , the angles made with [ 111 ]

For each ( 111 ) -direction the m3m symmetry reduces to the 3m point group , by
applying which we obtain two orientationally inequivalent octahedra per axis : a
total of eight orientational types in the unit cell . In fig . 12c ) , the orientation of the
