The paper is devoted to the investigation of ion composition of plasma of dc pulsed magnetron discharge generated by a magnetron with Al target in an Ar/O2 mixture. The magnetron discharge was investigated in the non-reactive, metallic and oxide mode of sputtering using a mass spectrometer. The amount and energies of neutral oxygen atoms O,positive O+ and O2+ ions, and negative O- and O2- ions were measured as a function of oxygen flow rate φO2, magnetron voltage Ud and constant power Pd=400W delivered to the magnetron discharge, repetition frequency of pulses f=10 kHz and the ratio of O2 and Ar flow rates φO2=φAr. The content of ions and radicals in magnetron discharge is compared with optical spectroscopy measurements. The obtained results give a deeper insight into reactive magnetron sputtering of oxide films.
