Enhanced dielectric performance of Y3Fe5O12 via incorporating LiFe5O8 thin film
Y3Fe5O12 (YIG) dielectric material has recently attracted much attention in microwave applications, where improving permittivity and reducing dielectric loss is crucial. In this work, the LiFe5O8/Y3Fe5O12 (LFO/YIG) composite dielectric film was fabricated by the chemical solution deposition method. The introduction of LFO thin film into YIG formed defect dipoles and established an internal electric field, thus enhancing dielectric performance. The permittivity of the LFO/YIG composite film is 19.49 at 1 kHz, which is twice that of pure YIG film, and the dielectric loss is also reduced from 1.01 to 0.47. Meanwhile, the response characteristics of the composite film to the bias field exhibit asymmetric behavior. In comparison to the single YIG film, the LFO/YIG composite film shows good thermal stability.
