资源简介:
Magnetic properties of iron-doped glasses and glass-ceramics were studied. Two different sets of glass samples were prepared. The first group of samples has the composition of (50 − 0.5x)SiO2–(50 − 0.5x)PbO– xFe2O3, where x = 15 and 20 (in mol%). Composition of the second group was 50SiO2–(50−x)PbO–xFe2O3, where x=15, 20 and 25 (in mol%). All sampleswere prepared by the conventional melt quenching technique; the melting was conducted in air at 1623 K in alumina crucibles. The melts were poured on a brass plate preheated to 573 K and formed into button-shaped samples. Afterwards pellets were annealed at 673K, cooledwith the furnace and polished to the thickness of about 1mm. Magnetic properties were analyzed by magnetic force microscopy (MFM) NT-MDT Ntegra.
