Title

Structures and magnetism of the Li/ammonia intercalates of Fe3GeTe2 and Fe5GeTe2

Abstract

This proposal is to measure the crystal and magnetic structures of new intercalates of the topical layered ferromagnets Fe3GeTe2 and Fe5GeTe2 obtained by intercalating lithium and ammonia between the iron germanium telluride slabs. The use of neutrons will enable location of light atoms of the intercalate and the measurement of additional low temperature magnetic Bragg scattering. These are chemical derivatives of a topical series of layered ferromagnetic compounds which offer a new route to property tuning.
