Magnetic disorder in the Cu0.995Fe0.005O solid solution

The magnetic hyperfine field, measured by Moessbauer spectroscopy, of a Cu(Fe)O solid solution displays a spin-glass-like behaviour that undergoes two transitions. The samples were produced by a 48 h ball-milling and 40 h successive annealing treatments at 650, 700 and 800 K with 0.25 mol% of α-57Fe2O3 and CuO. The signal shows a magnetic splitting that develops at temperatures lower than ca. 150 K. The measured distribution of hyperfine fields broadens at lower temperatures and its behaviour down to 15 K extrapolates to a saturation field of ≈29 T. The second transition takes place at temperatures between 4.2 and 15 K. The observed magnetic behaviour is interpreted in terms of magnetic disorder and canted local states of the system of magnetic moments.

Role of compensating Li/Fe incorporation in Cu0.945Fe0.055- xLixO: Structural, vibrational and magnetic properties

Doped transition metal oxides, like CuO, are spintronic materials. An increase of magnetic moment has been reported in Fe-doped CuO.1 Additional secondary doping elements such as Li may further modify magnetism in transition metal oxides2,3 due to changes

X-ray structural studies on solubility of Fe substituted CuO

CuO is a promising material for the spintronic industry for which lattice distortions/defects play an important role in determining its magnetic and various other physical properties. The ionic radii and charge of Cu2+[vi] (0.73 ?) and Fe3+[vi] (0.64 ?) are quite different. Hence high Fe substitution in CuO in place of Cu may generate strain/distortions. Fe substitution may enhance magnetic properties, even at room temperature, making such materials interesting for device applications. A detailed structural study on Fe incorporated CuO lattices to confirm phase purity, supported by evidence of the absence of a secondary phase is absolutely essential especially when considering a considerable substitution of up to ～12.5%. The electronic valence state, fine structure and local neighborhood/geometry of constituent elements need to be investigated using synchrotron based X-ray absorption spectroscopy (XAS). We report, for the first time, such a detailed study on understanding this magnetically and electronically important material: Cu1-xFexO, 0 ≤ x ≤ 0.125.
