The heavy-fermion superconductivity in CePtSi with a non-centrosymmetric structure attracts a lot of attention since novel superconducting properties are expected under this symmetry. Another characteristics of the superconductivity in CePtSi is its coexistence with long-range antiferromagnetic order. Therefore detailed antiferromagnetic properties and its interplay with superconductivity are of strong interest to investigate. The magnetic structure of CePtSi is represented by =(0,0,1/2). We have observed that the 0 0 1/2 antiferromagnetic reflection exhibits a peculiar response to an external magnetic field; its intensity increases with magnetic fields. These results imply unusual antiferromagnetism in CePtSi.
