Nanostructured solid solutions of the composition Zn1-xFexO (0 ≤ x ≤ 0.075) with tubular aggregate morphology, synthesized by the precursor method, were subjected to thermobaric treatment at P = 5 GPa and T = 600-700 °C. Using the samples with x = 0.05 as an example, it was shown that the application of pressure leads to morphology variation, reduction of structural parameters and to an increase in ferromagnetism.
Keywords: High pressure – high temperature, nanomaterials, glycolate, semiconductors.
