The present work describes a procedure for the preparation of iron oxide and carbide nanoparticles in carbon nanotube (CNT) matrix using the wet impregnation method and subsequent heat treatment in different atmosphere. In this way; two specific composites were produced with magnetite and cementite phase particles dispersed in CNTs; respectively; and cementite particles were encapsulated in graphene shells. As-prepared nanoparticles were all single crystalline and characterized by transmission electron microscopy (TEM); high-resolution TEM and X-ray diffraction. The magnetic properties of the resultant products were studied using vibrating sample magnetometer at room temperature. © 2007 Elsevier B.V. All rights reserved;
