Ferrites nanoparticles MFe₂O₄ (M = Ni and Zn): hydrothermal synthesis and magnetic properties

Boletín de la Sociedad Española de Cerámica y Vidrio, 2008
MFe2O4 (M = Ni and Zn) nanoparticles were prepared by the hydrothermal method. The obtained samples were characterized by X-ray and electron diffraction, Scanning and Transmission Electron Microscopy and Mössbauer spectroscopy.

Transition Metal-Doped ZnO and ZrO₂ Nanocrystals: Correlations Between Structure, Magnetism, and Vibrational Properties—A Review

Applied Sciences
Transition metal (TM)-doped zinc oxide (ZnO) and zirconium dioxide (ZrO2) nanocrystals exhibit complex correlations between crystal structure, defect chemistry, vibrational properties, and magnetic behavior that are strongly governed by synthesis route ...

Novel Aspects of Magnetic Interactions in a Macroscopic 3D Nanoparticle-Based Crystal

, 2010
We report magnetic measurements on a macroscopic three-dimensional fcc array of iron-oxide nanoparticles. We observe typical nanomagnetism for the randomly packed configuration of nanoparticles, including dynamical freezing and superparamagnetism.

Nanocrystalline magnetic glass-coated microwires using the effect of superparamagnetism are usable as temperature sensors in biomedical applications

, 2019
For the control and study of the post-implantation biomechanical processes of TiAlV implants, the ability of wireless in vivo measurement of various parameters (i.e., temperature in this case) at the tissue-implant interface is required.
