摘要：

Two phase transitions near 35 and 24 K can be detected in the specific heat, susceptibility, and resistivity of CeRh2Si2. 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 CeRh2Si2 clarifies a controversy surrounding observations by neutron diffraction.
