A review is given of some low-frequency and d.c. magnetic resonance phenomena studied since 1970s up to date. The content includes: the enhanced longitudinal susceptibility effect (ELSE) based on the concept of the dipole-dipole reservoir in EPR; direct registration of NMR in rotating frames; modulation method of measuring extremely fast electron spin longitudinal relaxation; resonance magnetoresistance and resonance spin rectification ('spin dynamo') in conducting ferromagnetic films. Physical mechanism of these effects, as well as applications in studying spin dynamics and relaxation in solids, including dynamic nuclear polarization, high-temperature superconductivity and properties of rare-earth manganites are considered.
