Abstract

Neutron scattering is a powerful tool for revealing magnetic structures of both single crystal and powder materials. By combining neutron scattering with other measurements such as AC and DC susceptibility, magnetization, specific heat, and resistivity, it is possible to unearth the magnetic properties of many materials. Neutron scattering is especially useful in the examination of geometrically frustrated materials, where the competition between interactions can yield a variety of interesting magnetic ground states. For complex or incommensurate structures, single crystal neutron diffraction is a powerful tool able to resolve intricacies not possible with powder measurements. Here, neutron scattering techniques are examined and used in combination with other measurements to examine two-dimensional frustrated triangular compounds and 3d-transition metal monophosphides with a double helical structure.
