- Аннотация: Metastable cubic Fe1-xZnxO solid solutions (0 < x ≤ 0.5) with a rock salt structure (Fm-3m) have been synthesized by a solid-phase reaction between wurtzite ZnO and cubic FeO at 7.7 GPa and 1500 K. The magnetic and transport properties of these solid solutions were studied at ambient pressure over the temperature range of 4.2–300 K, and the presence of antiferromagnetic order has been revealed with a decrease of the Néel temperature from 112 K for Fe0.7Zn0.3O down to 45 K for Fe0.5Zn0.5O. Synthesized rock salt Fe1-xZnxO solid solutions exhibit semiconducting behavior with low electrical resistivity (at 300 K, from 0.37 Ohm∙cm for x = 0 to 28 Ohm∙cm for x = 0.5) and p-type conductivity due to the presence of a deep defect level with an activation energy of 105–144 meV located above the top of the valence band.
