Abstract:
Two-dimensional rare earth (RE)-based honeycomb lattice magnets provide a fertile platform for exploring exotic magnetic ground states in view of reduced spatial dimensionality and anisotropic exchange interactions, while the reported 2D honeycomb lattice materials are quite limited. Herein, we report a family of quasi-two-dimensional layered RE-based honeycomb lattice magnets RE2Te4O11 (RE = Gd-Er and Yb), where the magnetic honeycomb layers are well separated by nonmagnetic TeO4 polyhedra with large interlayer distances of 8.353-8.452 Å. Magnetic susceptibility characterizations reveal that all synthesized RE2Te4O11 (RE = Gd-Er and Yb) compounds exhibit dominant antiferromagnetic (AFM) interactions; three RE2Te4O11 (RE = Gd, Tb, and Dy) family members show magnetic transitions with Néel temperatures (TN) of 1.97, 3.61, and 2.52 K, respectively. For Tb2Te4O11, a field-induced spin-flop transition is observed below TN = 3.61 K in the isothermal magnetization M(B) curves. Based on the analysis of the magnetocaloric effect (MCE), a crossover behavior is observed from the inverse MCE at low fields (ΔB < 1.8 T) to conventional MCE at high fields (ΔB > 1.8 T) below the TN in Tb2Te4O11; this is in contrast to the conventional MCE in all measured field regions in other RE2Te4O11 compounds.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

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...

02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
