NEUTRON DIFFRACTION INVESTIGATION OF ANTIFERROMAGNETISM IN CrCl$sub 3$
Journal Article

· Phys. and Chem. Solids
Observations were made on powder and single crystal samples of anhydrous CrCl/sub 3/ at temperatures from 298 to 4.2 deg K. This hexagonal layer-type crystal undergoes a transition at 16.8 deg K to an antiferromagnetic state in which the magnetic moments within each hexagonal layer of metal ions are aligned parallel but adjacent layers of moments are oppositely directed. The axis of spontaneous sublattice magnetization is closely perpendicular to the c-axis. Observations of the (003) antiferromagnetic reflection in an external magnetic field show that the antiferromagnetism can be destroyed with fields of only a few kilo-gauss, and lead to the conclusion that a net magnetization can be produced with very small magnetic fields.
