摘要：

In order to investigate the giant magnetic moment problem in nano-fine Pd alloys particles, enough amount of Pd/Ni fine particles with quite narrow diameter distribution have been prepared by chemical method. The magnetization of Pd/Ni alloy ultrafine particles has been systematically investigated by using a SQUID magnetometer. The magnetization remarkably increases above the concentration of 8% of Ni. This result indicates the giant moment in the ultrafine Pd/Ni alloy particles. (C) 1998 Elsevier Science B.V. All rights reserved.
