These composites are investigated for their structural, micro-structural, dielectric, ferroelectric and magneto-dielectric properties. X-ray diffraction shows the presence of the peaks corresponding to both ferroelectric and ferrite phases in the composites. Temperature dependent dielectric spectra gives the two anomalies one at lower temperature (below 50&deg;C) corresponds to the ferroelectric transition temperature and other at the higher temperature (above 350&deg;C) corresponding to magnetic transition. The variation of dielectric constant and loss tangent with applied magnetic field between 0-1 tesla in the frequency range of 500 Hz to 1 MHz are investigated. Dielectric constant possesses contribution due to magnetic field dependent interfacial polarization and variations due to the induced stress which can be explained on the observed MD effect.&nbsp;}, keywords = {BZT-CNFO,Multiferroics,Magneto-dielectric,hydroxide co-precipitation,microwave sintering}, url = {https://amp.iaamonline.org/article_15951.html}, eprint = {} }
