“…The appearance of competing AFM interactions in the triangular lattice leads to the magnetic fluctuations. 56–58 Considering that the AFM coupling strength ( J 3 ) between the TNN Fe atoms is the weakest, the spin orientations of three Fe atoms in the triangular sublattices follow the stronger J 1 and J 2 , corresponding to the AFM2 configuration.…”

“…One of the most typical features of such frustrated magnetic systems is the existence of only one phase even in the presence of the external magnetic field, which transforms into the corresponding discrete system of well-defined plateau and single-point ground states in the zero temperature limit (see, e.g. [19][20][21][22][23][24][25]).…”

The influence of the single-ion anisotropy on the thermodynamic properties of ferromagnetic as well as ferrimagnetic spin-1/2 − 1 mixed systems on the square and simple cubic lattice is investigated in the framework of the exactly solvable Ising-like models on the corresponding recursive lattices. The exact solutions of the models are present in the form of the explicit expressions for the free energy per site as the functions of the coordinates of the fixed points of the corresponding systems of recursion relations. The phase diagrams of the models are determined and the existence of compensation temperatures in the ferrimagnetic cases are discussed. The equations that drive the positions of the critical points are derived. The existence of the tricritical behavior in the three-dimensional system on the simple cubic lattice and its nonexistence in the case of the two-dimensional system on the square lattice is demonstrated. It is shown that the presence of the single-ion anisotropy can naturally lead to the emergence of the thermodynamic anomalies typical for frustrated magnetic systems even in unfrustrated ferromagnetic systems on studied bipartite lattices. First of all, the studied models exhibit the formation of strict residual-entropy hierarchies between the neighboring ground states of the system of three different ground states. It is also shown that due to this behavior of the entropy the specific heat capacity of the models exhibit anomalous (Schottky) behavior at low temperatures in the vicinity of the values of the anisotropy parameter, for which highly macroscopically degenerated single-point-like ground states are formed.
