Abstract

A new designed Bi₂O₃-B₂O₃-BaO-Fe₂O₃ magnetic glass-ceramic braze was developed to fabricate yttrium iron garnet ferrite (YIG) integrated structure. The magnetism level of the glass braze was controlled by in-situ crystallization of magnetic phase BaFe₁₂O₁₉ and transitional phases. The saturation magnetization intensity of the glass brazes reached its maximum of 7.83 emu/g after designed heat-treatment for crystallization. YIG/BBBF glass/YIG joints showed not only outstanding mechanical strength but also desirable magnetic performance. The shear strength of the joints was up to 62.6 MPa, and the saturation magnetization intensity of the joints was up to 97% of YIG base material, which indicated almost no attenuation of the joints' magnetic performance compared with YIG base material. The mechanisms of the target magnetic phase BaFe₁₂O₁₉ on the mechanical and magnetic performance of the joints were deeply elaborated, laying theoretical foundation for the magnetic control of ferrite device joints.
