Abstract
Small particles of BaFe12O19 are prepared at low temperature by a liquid mix technique. By using X-ray diffraction, Mössbauer, and magnetic measurements we show that this method allows an easy control of the size and shape (400 Å-3 000 Å) of the particles, which display essentially bulk magnetic properties.
