摘要：In this paper, microwave sintering (MS) technology has been applied in the preparation of ferromagnetic-ferroelectric composites. Several kinds of (Ni0.3Zn0.6Cu0.1)Fe2O4 (NiCuZn) ferrite with different contents of BaTiO3(BT) have been fabricated by MS technology. We found that the sintering time and temperature were significantly reduced from 22 h and 1100 degrees C for the conventional sintering (CS) process to 2 h and 840 degrees C for MS process, respectively. Experiments show that MS treated NiCuZn-BT composites possess both excellent ferromagnetic and ferroelectric properties. For the composites of NiCuZn added with 15% BaTiO3, the real part of permittivity is larger than 50 below 20 MHz and the real part of dielectric constant is larger than 18 below 1 GHz. Our results indicate that the microwave sintering method is a potential important technique in LTCC technology. (c) 2011 American Institute of Physics. [doi: 10.1063/1.3564965]
