Sk. Ma et Jt. Lue, SPIN-GLASS STATES EXHIBITED BY SILVER NANO-PARTICLES PREPARED BY SOL-GEL METHOD, Solid state communications, 97(11), 1996, pp. 979-983
Short-ranged local magnetic moments manifesting a cusp in the magnetic
susceptibility measurements are found to exist in silver nano-particl
es embedded in SiO2 glass prepared by sol-gel method. The spin-glass s
tates occur occasionally only for samples with diluted fine nanometer
size.
