Abstract

Transmission Electron Microscopy(TEM) and magnetization measurements were used to study the correlation between size of the iron particles precipitated in glass and their magnetic properties. The iron particles les s than 40 Å in diameter photodeposited in porous Vycor glass(PVG) show superparamagnetic behavior at room temperature. As the size of the particles increases and reaches about 100 Å in diameter, the magnetization curve shows minor hysteresis with a very large coercivity.
