概要

• 論文の詳細を見る

• The magnetic structure as well as the exchange parameters in MnGeO_3 with the ilmenite structure have been investigated by neutron diffraction and paramagnetic scattering using powder sample prepared at 100℃ under high pressure of 50 kbar. It has been found that the crystal has the same antiferromagnetic structure as MnTiO_3; the spins are directed along the [111] rhombohedral axis and are aligned in antiparallel in the layer. The nearest neighbor Mn^<2+> distance is 3.02Å and the exchange integral J_1 between them is found to be 0.84±0.01 meV.
