Predoi et al (2003 J. Phys.: Condens. Matter 15 1797) analysed Mossbauer spectra of powders of γ-Fe2O3 particles with a varying degree of hydration or with sulfate coating in terms of surface effects, superparamagnetic relaxation, and inter-particle

Spin-canting in spinel nanoparticles of maghemite has multiple origins, among which surface effects, finite-size effects or chemical disorder effects. XMCD at the Fe L 2 , 3 edges allows to separate the contributions of the magnetic moments of Fe 3 +

From AC susceptibility, magnetization and Mossbauer spectroscopy measurements, we show the dominant role of the surface properties and surface-to-core exchange coupling on the static and dynamic properties of γ-Fe 2 O 3 particles (2.7, 4.6 and 8.7 n

Samples of γ-Fe2O3 nano-particles with a mean size of 4.0(3) nm and with different hydration and surfactant degrees were prepared by sol–gel methods. Morphology and structural data were obtained by transmission electron microscopy and x-ray diffra

Powder oxides with the formula YFe 1– x Cr x O 3 (0.5≤ x ≤1) have been studied. The samples have been prepared using the ceramic solid state reaction in air. The X-ray diffraction spectra indicated that the samples crystallise in the perovskite
