“…The values of M for x = 0.8, 0.9 and 1.0 decrease rapidly at respective T N . FePS 3 is known to have magnetic anisotropy due to the crystal electric field effect and the antiferromagnetic transition which is accompanied by the magnetoelastic effect [12,13]. The origin of rapid decrease at T N for x = 0.8 and 0.9 is also attributed to the same reason.…”

“…Allowing for inequivalent exchange interactions between equivalent neighbors might be a consideration. This may be justified as the magnetic phase transition is believed to be first order, with a concomitant distortion of the lattice at T N as observed in x-ray diffraction [18,41].…”

Neutron scattering from single crystals has been used to determine the magnetic structure and magnon dynamics of FePS 3 , an S = 2 Ising-like quasi-two-dimensional antiferromagnet with a honeycomb lattice. The magnetic structure has been confirmed to have a magnetic propagation vector of k M = [ 01 1 2 ] and the moments are collinear with the normal to the ab planes. The magnon data could be modeled using a Heisenberg Hamiltonian with a single-ion anisotropy. Magnetic interactions up to the third in-plane nearest neighbor needed to be included for a suitable fit. The best fit parameters for the in-plane exchange interactions were J 1 = 1.46, J 2 = −0.04, and J 3 = −0.96 meV. The single-ion anisotropy is large, = 2.66 meV, explaining the Ising-like behavior of the magnetism in the compound. The interlayer exchange is very small, J = −0.0073 meV, proving that FePS 3 is a very good approximation to a two-dimensional magnet.

“…Once the van der Waals forces holding the layers of the host together are destroyed, 1,10-phenanthroline is much more easily inserted into the layers in a fast reaction, in which the guest is arranged perpendicular to the layer due to the restriction of limited interlayer space of the host (Eq. [4] in Fig. 4).…”

“…Equation [3]: the slower intercalation, in which the protonated 1,10-phenanthroline inserted into the layer to balance charge neutrality is arranged parallel to the layer of the host. Equation [4]: the faster intercalation, where the three phases coexist during the intercalation. Equation [5]: the orientation of the guest controlled by the amount of phenanthroline in the reaction, in which there was a reversible process: (a) molecular ring of phenanthroline is parallel to the layer of the host; (b) the parallel and perpendicular molecular rings of phenanthroline coexist; (c) the 1,10-phenanthroline ring was oriented so that the molecular twofold axis is perpendicular to the layer of the host.…”
