In the present paper, DC magnetization investigation on the insulating nanocrystalline powder samples of Ti1−xMnxO₂ (x = 0, 0.05, 0.10, and 0.15) prepared by simple chemical route is reported. Structural measurements revealed phase pure anatase structure of TiO₂ when x ≤ 0.05 and a mixture of anatase and rutile TiO₂ along with the...

The magnetic induction in superlattices comprising thin layers of the high-Tc superconductor YBa2Cu3O7 (YBCO) and the ferromagnet La2/3Ca1/3MnO3 (LCMO) has been investigated by polarised neutron reflectometry measurements. The data provide evidence for a surprisingly strong mutual interaction of the superconducting and the ferromagnetic order parameters. In the region of the interfaces a...

Form factor and magnetic properties of silica-coated spindle-type hematite nanoparticles are determined from SAXS measurements with applied magnetic field and magnetometry measurements. The particle size, polydispersity and porosity are determined using a core−shell model for the form factor. The particles are found to align with their long axis perpendicular to the applied field. The...

Cobalt doped zinc oxide thin films have been deposited using spray pyrolysis method. These single phasic films exhibited [100] preferential texture and small decrease in the lattice parameter on cobalt substitution. The films having different Co concentration have almost similar surface morphology and microstructure. These Zn1−xCoxO (x ≤ 0.10) thin...
