  Trilayered, Ising, spin-1/2, ferrimagnets are an interesting subject for
simulational studies for they show compensation effect. A Monte Carlo study on
such a system with sublayers on triangular lattice is performed in the current
work. Three layers, making up the bulk, is formed completely by either A or B
type of atoms. The interactions between like atoms (A-A; B-B) are ferromagnetic
and between unlike ones (A-B) are anti-ferromagnetic. Thus the system has three
coupling constants and manifests into two distinct trilayer compositions: AAB
and ABA. Metropolis single spin flip algorithm is employed for the simulation
and the location of the critical points (sublattice magnetisations vanish,
leading to zero bulk magnetisation) and the compensation points (bulk
magnetisation vanishes but nonzero sublattice magnetisations exist) are
estimated. Close range simulations with variable lattice sizes for compensation
point and Binder's cumulant crossing technique for critical points are employed
for analysis and conditions for the existence of compensation points are
determined. Comprehensive phase diagrams are obtained in the Hamiltonian
parameter space and morphological studies at critical and compensation
temperatures for both the configurations are also reported. The alternative
description in terms of Inverse absolute of reduced residual magnetisation and
Temperature interval between Critical and Compensation temperatures is also
proposed and compared with traditional simulational results. Such simulational
studies and the proposed systematics of compensation effect are useful in
designing materials for specific technological applications.
