摘要：

Ag-Mn nanoparticles were prepared by advanced gas evaporation. Their composition corresponded to Ag0.89Mn0.11, and the particle size distribution was log normal. The particles demonstrated an unambiguous spin glass behavior with the temperature dependent magnetic susceptibility displaying a plateau at similar to 25 K. The magnetic domains were limited by the size of the particles. (C) 1999 American Institute of Physics. [S0021-8979(99)06623-2].
