Abstract
Neutron diffraction experiments have been performed on single crystalline samples of CePtSi3. We found that the incommensurate magnetic propagation vector τ1 = (±0.283, 0, 0) in the phase I (2.2 ∼ 4.8 K) switches to the commensurate vectors τ2 = (±0.25, 0, 0) and τ3 = (±0.25, 0, ±1) in the phase III (∼ 2.8 K) at zero field. Although the magnetic structure of CePtSi3 in the phase I is a spin density wave similar to those in CeRhSi3, CeIrSi3, and CePdSi3, the magnetic structure in the phase III is commensurate unlike other CeTSi3 (T = Rh, Ir, Pd) compounds.
