This chapter reviews briefly the theoretical and experimental studies of ferromagnetic resonance (FMR) in individual microwires and nanowires. It shows how microwave properties change when the wire diameter decreases below the electromagnetic skin depth. First the fundamentals of FMR in ferromagnetic metals are summarized, and the characteristic features of FMR in wires are pointed out. Then some measurement techniques and basic experimental configurations are described. The chapter discusses the theoretical models for parallel and transversal field configurations and compares them with the experimental results. Finally the nonlinear effects are mentioned, and their theoretical explanation, based on the Suhl spin-wave instabilities, is proposed.
