Abstract
A systematic pulsed nuclear magnetic resonance study was performed on a set of ultrafine platinum powder samples with mean particle diameters ranging from 33 A to 200 A. The particle size dependent NMR properties revealed Friedel oscillations of electron densities near the metal surface. No quantum size effect was found. It is suggested that 300 A diameter samples may be useful for thermometry in large magnetic fields at low temperatures.
