The effects of high magnetic field (10 T) on the products obtained by calcination of Co–Fe LDH precursors at different temperatures were investigated. The XRD results indicated that FeIII substituted for CoIII in Co3O4 to yield CoIICoIIIFeIIIO4 und

A magnetic field of 12 T was applied during the annealing of amorphous α-Fe 2 O 3 microspheres. The authors demonstrate that magnetic field processing leads to the formation of γ-Fe 2 O 3 phases in the microspheres, and the field-treated microspher

We present herein a comparison of the magnetic properties of bulk ceramics and thin films of the ferrimagnetic ErCo0.50Mn0.50O3 compound. Epitaxial thin films were deposited onto (1 0 0) SrTiO3 substrates by pulsed-laser ablation while bulk ceramics
