Neutron Diffraction Studies of a Nickel Zinc Ferrite
Abstract
Neutron diffraction studies have been made of a ferrite powder of composition Zn0.5Ni0.5Fe2O4. The crystal structure is of the spinel type with 4 Zn++ and 4 Fe+++ ions in the tetrahedral positions and 4 Ni++ and 12 Fe+++ ions in the octahedral positions. The magnetic structure at 25°C appears to have an antiparallel arrangement of the Fe+++ spins on the two sites and a random orientation of the Ni++ spins.
