In addition, they are employed in bio separation to isolate specific cells like proteins and DNA. Most common techniques like rapid solidification ,annealing and sintering usually use metals and ceramics are involved in phase transitions to create materials with specific high performance physical properties. Negative resonance of permittivity in metallic materials below plasma frequency as well as negative permeability of some ferromagnetic metals and metallic alloys exhibited importance of these materials to understand metamaterials. Such type of behavior emerged from negative dielectric that observed at low frequencies has a growing interest from researchers about phase transition that occurs close to resonant frequency even though, at certain frequencies dielectric constant becomes positive .Recent success and variety of polymeric materials in fabricating wide range of electronic devices made them highly recommended. Polymer matrix/host applications that utilizing elastomer polymers technology is widely used to create high strength and light weight materials for various industries. As a consequence, in this current study, a hosted matrix of silicon rubber elastomer was casted to ceramic filler nano powders barium titanates with contents(10,20,30 and 40wt.%).As it was purposefully planned to make use of multiferroic specific properties, volume of (1,3,5vol.%) iron were finally added as a strong ferromagnetic material to obtain the artificially hyper composite .This research study conducted thermal analysis, electrical and magnetic properties for prepared samples using different techniques including : thermogravimetric analysis (TGA) to study change in weight loss with effect of heat and time besides analyzing to what extent material stability affected by existence of elastomer. Dielectric constant έ ,dielectric loss ε’’ and electrical conductivity σ were also analyzed through frequency range (0.1M-1GHz). Negative resonance occurred in (3,5vol.%) samples of Fe-loaded hyper composite with values(-5.6 and − 8.5)at frequencies (1×10 6 and 1.09×10 7 Hz). Subsequently, magnetic parameters were also measured using Vibrating Sample Magnetometer (VSM) to hyper composite in magnetic field range from(-20000to20000)Gauss exhibiting a superparamagnetic magnetic behavior .
