Two phase transitions near 35 and 24 K can be detected in the specific heat, susceptibility, and resistivity of CeRh{sub 2}Si{sub 2}. We interpret the 35 K transition as magnetic ordering in a ( (1) /(2) (1) /(2) (1) /(2) ) structure. The much weaker transition near 24 K corresponds to the development of domains having a ( (1) /(2) (1) /(2) 0) magnetic structure that grow spatially at the expense of the ( (1) /(2) (1) /(2) (1) /(2) ) structure. This interpretation of the magnetic phase diagram of CeRh{sub 2}Si{sub 2} clarifies a controversy surrounding observations by neutron diffraction. {copyright} {ital 1998} {ital The American Physical Society}
