In manganites, the spin ordering depends on the orbitals in the e.. state of Mn ions. It isshown that the magnetization process is also strongly affected by the orbitals, by tzsing theexact diagonalization technique applied to the effective Hamiltonian which includes a couplingbetween the spin and orbital degrees of freedorn derived from strong on-site Coulomb interactionand orbital degeneracy of In Tons. We find that the spin moment induced by an applied magneticfield is accompanied with the change of the orbital structure. Stnch a coupling between the spinand orbital degrees of freedom results in a charasteristic magnetization process of manganites.Recent experimental data obtained in Prg.5Ca0.5[VInO3 and related compounds are examined inthe light of the present theory.
