Abstract
An electron spin resonance (ESR) investigation of Pt-nanoparticles electrodeposited in the channels of porous Al2O3 membranes has been performed in the temperature range 6 – 50 K. Pt – particle mean size was evaluated by means of Kawabata theory that relates ESR linewidth to metal particle size. A comparison with the effective crystallite mean size obtained from the X – ray diffraction analysis is given..
