A simplified statistical model fro amorphous antiferromagnets is presented. The model consist of Ising spins on a spatially random lattice in two-dimensions which is constructed by closely packing the plane with equilateral triangles and squares (triangular-square lattice). Several thermodynamic properties are studied by using the Monte Carlo method. It is found that the system exhibits a cooperative spin freezing phenomenon at a certain finite temperature, whereas the uniform susceptibility rises monotonically without any remarkable anomaly as the temperature is decreased. Relations with some experimental results for amorphous antiferromagnets are discussed.
