Zusammenfassung:The magnetic Bragg reflections of charge-stripe ordered La1.725Sr0.275NiO4 where investigated by neutron diffraction to determine the intensity ratio of first to third order harmonics. The third harmonic Bragg reflections were not observed at temperatures across that magnetically ordered phase, creating an upper bound for their intensity of 0.16% of the first harmonic intensity.
