Novel electronic properties of low-dimensional organic conductors under high magnetic fields are briefly reviewed and some topical problems are discussed. Magnetic field effects to electron spins and electron orbital motions are discussed in the quasi one-dimensional conductors (R 1R 2 DCNQI) 2Cu and (TMTSF) 2X and in the quasi two-dimensional conductor (BEDT-TTF) 2XHg(SCN) 4. Electronic properties in the anomalous state of (BEDT-TTF) 2KHg(SCN) 4 are discussed in the light of the angle dependent magnetoresistance oscillations. Properties of field-induced spin-density waves are studied in relation to the superlattice potential made by the anion ordering in (TMTSF) 2ClO 4. Possible origins of the rapid oscillations in magnetoresistance of (TMTSF) 2X are examined. Introduction is made to theoretical ideas of field-induced superconductivity and experimental trial to find it.
