摘要:
Two-line ferrihydrite particles are synthesized. Structural characterization of the sample is done with an X-ray diffractometer, transmission electron microscope, Fourier-transform infrared spectroscope, and thermogravimetric analyzer. Average particle size is 2 nm. Temperature variation (10-300 K) of zero-field-cooled and field-cooled susceptibility in 500 G applied magnetic field bifurcates at 50 K. The field-cooled susceptibility below this temperature is almost temperature independent. Magnetization versus applied magnetic field (0-120 kG) data at 300 K are analyzed considering particle size distribution.
