The Effect of Deuterium Absorption on Magnetic Ordering, Crystal Structure and Phase Transformations in Mn3Ga Materials.
Mn3Ga with the D022 structure has ferrimagnetic ordering whereas in Mn3Ga D019, triangular antiferromagnetic ordering is observed. Both of these structures have a low magnetic moment which makes them unsuitable as a permanent magnet material. Expansion of the crystal lattice by absorbing deuterium onto the interstitial sites strongly affects the magnetic coupling between the Mn atoms and may lead to a much higher magnetic moment. Neutron powder diffraction experiments are required to characterise the effect of deuterium absorption on the local magnetic moments in D019 and D022 Mn3Ga. Neutron thermodiffractometry will also be used to study the as yet unknown nature of the high temperature phase transformation in the system. The results will not only be critical to the developement of Mn3Ga-based materials as permanent magnets but will also contribute more detailed knowledge of the fundamental physical properties of the system.
