This chapter discusses one of the most fundamental properties of metal oxides (MOs): the spin state. Magnetism in MOs is provided by polarization of 3d states on the metal site. As crystal electric field (CEF) strength in 3d elements is strong compared to both spin orbit (SO) coupling and Zeeman interaction, the orbital moment is usually considered as ‘quenched', so that their total magnetic moment is governed by the spin moment only. Spin not only affects MO magnetic properties, but also structural stabilization and electronic or transport properties. The chapter focuses on the use of resonant inelastic X-ray scattering (RIXS), and presents the basic ideas about RIXS and its applications to spin properties. It also reviews remarkable results about spin-transitions in MOs as observed by RIXS. Construction of new synchrotron fs sources of high brilliance coupled to RIXS techniques will offer new opportunities for investigating ultra-fast spin-transition processes.
