摘要： A magnetic polymer composite comprising 60-90% by weight of the polymer, 10-40% by weight of magneto-resistive alloys and 5-30% by weight of the additive prepared by the process by dissolving 60-90% by weight of the polymer in a solvent to obtain a clear, colorless solution; adding 10-40% by weight of alloy and 5-30% by weight of the additive in the said clear color less solution; agitating the said clear, color less solution at a frequency of 15-20 kHz for a period of 5-30 minutes, to get equally dispersed alloy in the said polymer solution; transferring the said polymer solution with equally dispersed said magneto-resistive alloys and additive to the open non-metallic container on a magneto-stirrer allowing the said solvent to evaporate till the polymer coated transition metal based alloys are isolated in the form of cones from the said non-metallic container.
