摘要
Cobalt ions have been implanted at an energy of 160 keV at fluences of 2 x 10(16) 5 x 10(16) and 10(17) Co+ cm(-2) in silica layers and at temperatures of 77, 295 and 873 K. The nanocomposites formed have further been irradiated with electrons and swift heavy ions. Magnetic properties of the nanoparticles studied by a SQUID magnetometer at 295 and 5 K have been related to the modification of particle size and size distribution, which have been observed by transmission electron microscopy.
