摘要：

Mössbauer studies of ultrafine particles of iron are reported. The particles have an average diameter of 2 nm and they are dispersed in oil by a surface-active agent. The Mössbauer spectrum at 4.2 K cnsisted of a ferromagnetic and a paramagnetic component. The paramagnetic component was shown to disappear by keeping the sample at room temperature. It is deduced that particles having diameters less than a certain value are paramagnetic. © 1990 IEEE
