中文摘要	The orientation of Co/sub 3/O/sub 4/ thin films and their magnetic properties depend on the magnetic field strength during vacuum evaporation deposition of Co/sub 3/O/sub 4/ thin films. These effects were evaluated in the experiments using cobalt of 99.99% purity as the raw material and Si (111) as substrates. The evaporation pressure was 0.1 Pa and the magnetic fields were 0-4 T. The crystal size, orientation and magnetic performance were measured by scanning electronic microscope (SEM), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). Increasing the magnetic field from 0 T to 4 T reduced the grain size from 200 nm to 20 nm, H/sub c/ was reduced to 150 Oe and M/sub r//M/sub s/ was increased to 0. 81. The results indicate that high magnetic fields during evaporation deposition significantly influence the microstructure and crystal orientation of Co/sub 3/O/sub 4/ thin films and greatly improve M/sub r//M/sub s/.
