The electrochemical intercalation is one of most powerful tools for tuning the intrinsic properties of quasi-two-dimensional (2D) materials. In this work, ionic organic cations, [Formula: see text] and [Formula: see text], are successfully intercalated into [Formula: see text] interlayer via electrochemical intercalation. The both [Formula: see text] and [Formula: see text] intercalated [Formula: see text] samples show ferrimagnetic transition with the transition temperature of 65 K and 85 K, respectively. Raman spectroscopy, X-ray photoelectron spectroscopy and Hall measurements reveal that the electron doping and sulfur vacancies created by the cation intercalation play important role in the ferrimagnetic transition. Our work provides a new pathway to manipulation of magnetism in layered 2D materials.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
Ferromagnetism
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
