## Abstract We have studied the temperatureβdependent transport and magnetic properties of the nanocomposites, containing varied amounts of CoFe~2~O~4~, NiFe~2~O~4~, and Fe~3~O~4~ nanoparticles embedded in the conducting poly(3,4βethylenedioxythiophene) or PEDOT matrix, in the temperature range 77β
A new dual-phase nanocomposite magnet, made up of the well-coupled Sm 3 (Fe,Ti) 29 N x and β£-Fe nano-crystals, has been successfully fabricated by the melt-spun technique. Measurements of magnetic properties reveal that the hysteresis loop shows up the notable characteristics of single hard magnet i
