MAGNETISM OF RANDOMLY CANTED Li-Ti FERRITE

نویسنده

چکیده

FC-ZFC magnetisation, hysteresis, thermoremanence and neutron diffraction measurements were performed on Li1.125Feo.625Ti1.2504. The results are interpreted from domain and wall properties resulting of local canted state where the spin transverse component relaxes between preferential directions.

Li intercalation effects on magnetism in undoped and Co-doped anatase TiO2

The effects of n-type carrier doping by Li intercalation on magnetism in undoped and Co-doped anatase TiO2 are investigated. We have found that doped n-type carriers in TiO2 are localized mainly at Ti sites near the intercalated Li. With increasing the intercalation, local spins are realized at Ti. In the case of Co-doped TiO2, most of the added n-type carriers fill the Co 3d bands and the rest...

Effect of Acicular Ferrite on Cracking Sensibility in the Weld Metal of Q690+Q550 High Strength Steels

High strength steels Q690+Q550 were welded using three different welding wires without preheating by gas shielded arc welding process. Microstructural characteristics of weld metals and nucleation mechanism of acicular ferrite were investigated by means of scanning electron microscope (SEM), energy dispersive spectrum (EDS) and transmission electron microscope (TEM). The straight Y-groove test ...

Single-domain multiferroic BiFeO3 films

The strong coupling between antiferromagnetism and ferroelectricity at room temperature found in BiFeO3 generates high expectations for the design and development of technological devices with novel functionalities. However, the multi-domain nature of the material tends to nullify the properties of interest and complicates the thorough understanding of the mechanisms that are responsible for th...

Impact of interfacial coupling of oxygen octahedra on ferromagnetic order in La0.7Sr0.3MnO3/SrTiO3 heterostructures

La0.7Sr0.3MnO3, a half-metallic ferromagnet with full spin polarization, is generally used as a standard spin injector in heterostructures. However, the magnetism of La0.7Sr0.3MnO3 is strongly modified near interfaces, which was addressed as "dead-layer" phenomenon whose origin is still controversial. Here, both magnetic and structural properties of La0.7Sr0.3MnO3/SrTiO3 heterostructures were i...
