The nanostructure and magnetic properties of Fe69Co31 nanowire arrays with high energy product have been studied. Investigation results revealed a dense and continuous individual nanowire containing a number of defects. After annealing at 550 C, the nanowire arrays had a coercivity of Hc

A simple hydrothermal route, using cetyltrimethylammonium bromide (CTAB) as the surfactant, has been proposed for synthesizing single-crystalline spinal cobalt ferrite (CoFe2O4) nanorods. Transmission electron microscope (TEM) and scanning electron microscopy (SEM) images indicated that the final product consists of nanorods with a diameter of about 25nm andlength up to about 120 nm.Furthermore, high-resolution TEM (HRTEM) revealeda clear lattice structure of the [1 0 0] planes in the nanorods. The magnetic properties of the CoFe2O4 nanorods were characterized using vibrating sample magnetometer (VSM). The possible formation mechanism for the CTAB-assistedhyd rothermal synthesis of CoFe2O4 nanorods has been discussed.

【期刊论文】The magnetic phase transition and the low-field Arrott plots of (GDxDy1 x)Co2 compounds

A series of (GdxDy1-x)Co2 (0-0.55) compounds have been prepared by arc-melting method. In order to determine the phase transition order in these compounds, we have performed some magnetization measurements. Only from the plots of temperature dependence of magnetization and the low-field magnetization isotherms, it is difficult to judge the phase transition order. The low-field Arrott plot is proved to be a more reliable method to characterize the first-order transition and the second-order transition. No first-order transition is observed in (GdxDy1 x)Co2 compounds (xa0). The result is discussed in the Inoue-Shimizu like model.
