Abstract

The layered MIIPS3 compounds posess a unique cation exchange intercalation chemistry, which allows the synthesis of a wide range of air stable M1-xPS3G2x intercalates (G stands here for a Monocation). The positive charge of the guest cations is counterbalanced by intralayer metallic vacancies.

Intercalation exerts a dramatic influence on the magnetic properties of these compounds. Whereas pristine MPS3 compounds order antiferromagnetically (M = Mn, Fe‥), Many intercalates become magnets below an ordering temperature that can be as high as 92 K. The role of intercalation is discussed in terms of the creation of intralayer metallic vacancies, which destroy the spin balance that prevails in pristine MPS3 compounds.

The MPS3 host lattice has the capability of causing spontaneous poling of the dimethylamino-N-Methyl stilbazolium chromophore (DAMS), leading to materials that exhibit strong second harmonic generation. (SHG). Inserting DAMS into MnPS3 therefore leads to a composite that possess both spontaneous Magnetization (below Tc = 40 K) and a strong efficiency for SHG.
