  A spin-1/2, Ising trilayered ferrimagnetic system on square Bravais lattice
is studied, employing Monte-Carlo simulation with the single spin-flip
Metropolis algorithm. The bulk of such a system is formed by three layers, each
of which is composed entirely either by A or B type of atoms, resulting in two
distinct compositions: ABA and AAB and two different types of magnetic
interactions: ferromagnetic between like atoms and antiferromagnetic between
unlike atoms. For such systems, Inverse Absolute of Reduced Residual
Magnetisation is the absolute value of the ratio of the extremum of the
magnetisation in between compensation and critical points and the saturation
magnetisation. Variation of relative interaction strengths in the Hamiltonian,
for a range of values, leads to the shift of compensation point and critical
point and changes in the magnitude of Inverse absolute of Reduced Residual
magnetisation. Probable mathematical forms of dependences of the Inverse
absolute of Reduced Residual magnetisation and temperature interval between the
compensation and critical points on controlling parameters were proposed in the
absence of applied magnetic field and have obtained phase diagrams for both
types of configurations from these relations. This alternative description of
the simulated systems may help technologists design magnetocaloric materials
according to desired characteristics.
