Properties of non-crystalline EulG and DylG obtained from Mossbauer and magnetization data

چکیده
The well-known dependence on preparation conditions of the microstructural polymorphism in nc networks is often also reflected in their magnetic properties. This is particularly evident for non-metallic nc materials where superexchange coupling dominates. The latter is very sensitive to slight variations in bond lengths and angles. For example. this counterplay of local structural and magnetic properties has successfully been investigated by Mossbauer spectroscopy on nc ferrous halides l-3. Here we report about the characterization of nc EuIG and DyIG with the help of Mossbauer and macroscopic magnetization measurements.

The nano-crystalline nickel-zinc ferrite was prepared via chemical synthesis. Zinc nitrate, nickel nitrate, iron nitrate hydrate, citric acid and ethylene glycol were used as precursor materials. Crystallization behavior of the precursor was studied by X-ray diffraction (XRD). Nanoparticle phases can change amorphous to spinel ferrite depending on the calcination temperature and crystallite siz...
متن کاملSusceptibility of non-crystalline ferromagnetic FeF2
2014 In the temperature range 150 K > T > 25 K the magnetic susceptibility of noncrystalline FeF2 can be described by a Curie-Weiss law. A paramagnetic Curie temperature of 03B8 = (22 ± 1) K and an effective moment of peff = (5.2 ± 0.1) 03BCB are found. Temperature and field dependence of the magnetization between 15 K-20.5 K indicate superparamagnetic behaviour. At lower temperatures...

The magnetic properties of calcined cobalt ferrite formed by nano-crystalline powders have been compared by two different methods (co-precipitation and hydrothermal). The structural properties of the produced powders were investigated by X-ray Diffraction (XRD), scanning electron microscopy (SEM). The results show that the formation of cobalt ferrite spinel structures is effected by changing me...
