Influence of Thickness on the Magnetic and Magnetotransport Properties of Epitaxial LaSrMnO Films Deposited on STO (0 0 1).

Epitaxial LaSrMnO films with different thicknesses (9-90 nm) were deposited on SrTiO (0 0 1) substrates by pulsed laser deposition. The films have been investigated with respect to morpho-structural, magnetic, and magneto-transport properties, which have been proven to be thickness dependent. Magnetic contributions with different switching mechanisms were evidenced, depending on the perovskite film thickness.

Tuning structural and magnetic properties of Fe oxide nanoparticles by specific hydrogenation treatments.

Structural and magnetic properties of Fe oxide nanoparticles prepared by laser pyrolysis and annealed in high pressure hydrogen atmosphere were investigated. The annealing treatments were performed at 200 °C (sample A200C) and 300 °C (sample A300C). The as prepared sample, A, consists of nanoparticles with ~ 4 nm mean particle size and contains C (~ 11 at.

Lead-Free BNT-BT/CoFeO Core-Shell Nanostructures with Potential Multifunctional Applications.

Herein we report on novel multiferroic core-shell nanostructures of cobalt ferrite (CoFeO)-bismuth, sodium titanate doped with barium titanate (BNT-BT), prepared by a two-step wet chemical procedure, using the sol-gel technique. The fraction of CoFeO was varied from 1:0.5 to 1:1.
