Abstract
Many properties of the spin -half kagome Heisenberg antiferromagnet remains controversial and receiving continuous attention from theorists and experimentalists due to their fascinating magnetic properties and high heterogeneity coax by the geometrical frustration.
In this research we seek and compare the results obtained in our recent article with that of Napel where we elucidate some of the identified magnetic behaviour using the spin Heisenbeg model with the application of Exact Diagonalization and classical Monte-Carlo simulation on three site dimer and 3D simple cubic lattice simulation.
The results obtained shows excellent agreement in both papers reviewed with our resluts establishing firmly the FM to AFM transition, having a clear transition point referred to mixed phased.
