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