| dc.description | We present in this work a study on the magnetic properties of nanocrystals of Mn- or Co-doped ZnO obtained by a proteic sol-gel process. Analysis of these nanocrystals is accomplished using x-ray diffraction (XRD), the Rietveld refinement through using the General Structure Analysis System (GSAS) program, and magnetic measurements using a vibrating sample magnetometer (VSM). The samples of Zn<sub>0.9</sub>M<sub>0.1</sub>O (M Co or Mn) possess single phase crystals with a wurtzite structure (hexagonal) and a P63mc space group. The Zn<sub>0.9</sub>Co<sub>0.1</sub>O and Zn<sub>0.9</sub>Mn<sub>0.1</sub>O samples presented, at room temperature, the behavior of a soft ferromagnetic with a coercive field (Hc) of 336 Oe and 1240 Oe, respectively, and a remanent magnetization (Mr) of 5 and 2.5 memu/g, respectively. |
