Characteristics of hetero-interfaces between MnAs films and Mn–Zn ferrite

Characterization of heterointerfaces in GaAs/MnAs/MnZn-ferrite structures

“…In the case of growths of GaAs on the ferrite substrates, however, their crystalline qualities are rather poor because of larger lattice mismatch and special techniques such as insertion of a buffer layer are highly requested. Recently, we have found that high-quality manganese pnictide films can be grown epitaxially on MnZn ferrite [10][11][12][13]. Among manganese pnictides, MnAs is a promising candidate as a buffer layer for GaAs on MnZn ferrite because it shares the common elements (As and Mn) with GaAs and MnZn ferrite, respectively.…”
