  We study phase transitions and thermodynamic properties in the
two-dimensional antiferromagnetic Ising model with next-nearest-neighbor
interaction on a Kagome lattice by Monte Carlo simulations. A histogram data
analysis shows that a second order transition occurs in the model. From the
analysis of obtained data, we can assume that next-nearest-neighbor
ferromagnetic interactions in two-dimensional antiferromagnetic Ising model on
a Kagome lattice excite the occurrence of a second order transition and unusual
behavior of thermodynamic properties on the temperature dependence.
