PrCo2Si2 has a collinear antiferromagnetic structure with a wave vector Q1 = (0, 0, 1) for T < T1 = 9 K, a high-order commensurate one with Q2 = (0,0,25/27) for T1 ≤ T < T2 = 17 K and with Q3 = (0,0,7/9) for T2 ≤ T < TN = 30 K. Molecular field calculations of the moment arrangements and magnetization processes of the compound were made with a molecular field model, and the field-temperature magnetic phase diagram was reproduced. The magnetic transitions are discussed in connection with the wave-dependent molecular field coefficients of the compound.
