The microwave-induced change of the magnetoresistivity of GaAs-GaInP heterostructures reveals resonant structure which is attributed to electron spin resonance of the two-dimensional conduction electrons. The spin splitting of the two lowest Landau levels has been investigated as a function of the magnetic field. From these studies the authors obtain the dependence of the g-factor on the magnetic field and the Landau level. These results are compared with those obtained in GaAs-AlGaAs heterostructures.
