We investigate low-temperature behaviors for an antiferromagnetic lsing model ofinfinite-spiua on the triangular lattice. The internal energy, the specific heat, and thespontaneous sublattice-magnetizations are calculated by Monte Carlo sinaulations atlow temperatures. The low-temperature expansions of the internal energy and thespecific heat are obtained from a low-temperature expansion of the free energy andshow excellent agreements with the results by the Monte Carlo simulations. The zero-temperature value of the specific heat is found to be equal to 2 /3. The effects of themisfits of the first order are discussed.ttriangular lattice, antiferromagnetic Ising model, infinite spin, Monte Carlo l[ simulations, low-texnperature expansion7
