“…2. It is essential to highlight that sublattice magnetization undergoes a first-order phase transition, achieving zero or a different value [14,25]. The sublattice magnetization can quickly altered that it does go to zero when the system transitions between two phases, separating the ferrimagnetic or antiferromagnetic phase from the paramagnetic phase.…”

“…Notably, in the case of ferrimagnetic materials, distinct indications of sublattice magnetizations are observed, and a point of compensation exists where the total longitudinal magnetization is precisely zero. The aggregate magnetization of the Ising model on a two-dimensional decorated triangular lattice (z=6; z is the number of nearest neighbours of the sublattice) is [13,14],…”

A decorated ferrimagnetic mixed triangular system was studied using the molecular mean-field approximation. The outcomes of the investigation were examined using the Blume-Capel Ising model. The study paper investigates the influence of crystal and external magnetic fields on ferrimagnetic devices decorated with mixed spin-2 and spin-7/2 of a triangular lattice. It is noteworthy that spin-2 ions are located at the nodal points, whereas six additional spin-7/2 ions surround the proposed lattice. Altering the exchange interactions through the specific crystal and external magnetic fields induces superparamagnetic behaviours. New characteristics reveal that mixed spin triangular decorated ferrimagnets exhibit superparamagnetic behaviour at DA∕|J2|=-2.5, with J1 = -0.5 and J2 = -1.0 in the range (15 ≤ KBT /|J2| ≤ 18). It is important to note that the total magnetization changes with the external magnetic field and affects the superparamagnetism phenomenon of a decorated mixed spin ferrimagnet when DA/|J2| = 8, and DB/|J2|=-11, J1 = -0.5 and J2 = 1, for KBT/|J2| = 2, 2.5, 3, 3.5, and 4 Ko respectively.

The same model on the nanowire geometry has been investigated by Monte Carlo simulation [22]. Spin (1/2-3/2) model on nanotube geometry has been investigated within the effective field theory [23] and on a nanowire geometry by Monte Carlo simulation [24,25].…”

The magneticaloric properties of the Ising nanotube constituted by arbitrary core spin values S c and the shell spin values S s have been investigated by mean field approximation. During this investigation, several quantities have been calculated, such as isothermal magnetic entropy change, full width at half maximum value and the refrigerant capacity. The variation of these quantities with the values of the spins and exchange interaction between the core and shell is determined. Besides, recently experimentally observed double peak behavior in the variation of the isothermal magnetic entropy change with the temperature is obtained for the nanotube.

The magnetocaloric properties - which is important for designing energy efficient and environment friendly heating and cooling systems- of the magnetic nanotube are constituted by arbitrary core spin values Sc and the shell spin values Ss have been investigated by mean field approximation. Several quantities have been calculated during this investigation, such as isothermal magnetic entropy change, full width at half maximum value and the refrigerant capacity, in order to suggest more efficient heating and cooling. The variation of these quantities with the values of the spins and exchange interaction between the core and shell is determined. Besides, recently experimentally observed double peak behavior in the variation of the isothermal magnetic entropy change with the temperature is obtained for the nanotube.
