The result of the neutrino magnetic moment measurement at the Kalinin Nuclear Power Plant (KNPP) with GEMMA spectrometer is presented. The antineutrino-electron scattering is investigated. A high-purity germanium detector with a mass of 1.5 kg placed at a distance of 13.9 m from the 3 reactor core is exposed to the antineutrino flux of 1/cm2/s. The recoil electron spectra taken in 18134 and 4487 hours for the reactor ON and OFF periods are compared. The upper limit for the neutrino magnetic moment at 90% C.L. is derived from the data processing.

• Neutrino non-standard interactions: A status report (2019, unknown): “The recent COHERENT data has put a bound on NMMs (μν ® 10μB) [273, 308], which is still weaker than the ν + e scattering bound obtained by GEMMA (μν ® 10μB) [314].”
