摘要：

Properties of colloidal suspensions of MnxFe1-xFe2O4 particles have been investigated using electron microscopy, magnetic measurements and de-susceptibility techniques. Effect of temperature on the magnetic properties of ferrofluids in both liquid and solid states has been studied. Analysis of the data yields information on the anisotropy constant, particle size distribution and superparamagnetic behaviour.
