The model generalizes the super-exchange model introduced by Fisher in 1960 and is analyzed in light of a free-fermion model. We deduce the critical condition and present detailed analyses of its thermodynamic and magnetic properties. The system is found to exhibit a second-order transition with logarithmic singularities at criticality.8 pages, 8 figures, references addedStatistical MechanicsSoluble kagome Ising model in a magnetic fieldtext
