Abstract

The magnetic properties of magnetite nanoparticles and magnetite- thermoplastic natural rubber (TPNR) nanocomposites was prepared by melt-blending method has been studied using vibrating sample magnetometer (VSM). The saturation magnetization (MS), remanence (MR), squareness (MR/MS), coercivity (HC) and exchange-bias field (Heb) for magnetite nanoparticles and its nanocomposites increased with decreasing temperature from 298 to 93 K. The increment of magnetization might be due to the decrease in thermal energy while the enhancement of coercivity and exchange-bias field is attributed to the exchange interaction at the interface between the ferromagnetic (Fe3O 4) and spin-glass-like surface layer on the nanocrystalline magnetite.
