• A method of determining the state of lowest energy of an Ising spin system under an external field is proposed. The energy of a spin arrangement is expressed in terms of the total number of negative spins and the numbers of interaction lines connecting either two negative spins or negative and positive spins. It is shown by use of topological relations among these numbers that the magnetization of an Ising spin antiferromagnet increases stepwise at absolute zero with increasing field strength. The spin arrangement at each step is determined of Oguchi and Takano's model of CoCl_2・2H_2O and the simple, body-centered, face-centered cubic and MnF_2 type lattices with nearest and next-nearest neighbor interactions. Experimental results of CoCl_2・2H_2O are discussed as well.
