Stress-induced relaxation mechanisms in single-crystalline titanomagnetites

The effect of titanium (Ti4+) substitution on slightly oxidized magnetite single crystals, Fe3-xTixO4+d—with and —is studied by means of magnetic after-effect (MAE) spectroscopy in the temperature range K. The MAE spectra corresponding to these, relatively high, substitution rates are characterized by the following items: (i) suppression of low-temperature (4
