“…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.…”
