 note = {We theoretically study effects on tunnel magnetoresistance (TMR) of spin configurations localized within insulating barriers. Two cases are treated herein: interaction between a tunneling electron and an isolated classical spin being canted at an angle to the magnetization axis of the ferromagnetic leads, and interaction between a tunneling electron and many quantum spins within the insulating barrier. The characteristic features of TMR observed in δ-doped ferromagnetic tunnel junctions and in grain boundaries of metallic manganites are discussed in view of the results obtained., 6pages},
