摘要：
I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La(2)CuO(4), (ii) orbital polaron when a hole is added to the alternating orbital (AO) ordered plane in LaMnO(3), and (iii) spin-orbital polaron when a hole is added to the AF and AO ordered plane in LaVO(3). Comparison of the distinct features of the above polarons can shed some light on the basic differences between the experimental phase diagrams of the lightly doped transition metal oxides La(2-x)Sr(x)CuO(4), La(1-x)Sr(x)MnO(3), and La(1-x)Sr(x)VO(3).
