Below TN, the NMR spectrum of 29Si in CePt3Si shows a rather narrow resonance line for the randomly oriented powder sample, while the oriented powder sample has a wide spectrum. To explain these spectra, a coexistence model composed of two phases was proposed. One phase is an ordinary AF state and the other is a paramagnetic like phase, in which the internal field is somewhat small. The AF internal field is expected to be parallel to the c-axis at Si site. This result cannot be explained by the magnetic structure obtained by the neutron diffraction experiment. [ABSTRACT FROM AUTHOR]
