Optical and magnetic properties of iron oxide nanoparticles in the potassium-aluminum-borate glass at thermoradiation treatment
Source abstract
Abstract
The paper presents the results of magnetic and optical studies of the 25K 2O•25Al 2O 3•50B 2O 3 glasses pure and with 0.1–3.0 wt% Fe 2O 3 additions subjected to thermoradiation treatment in a converging 60Co gamma field at a dose rate of 236 R/s and temperatures of 423–573 K. After the treatment the absorption spectra and magnetization were measured. The second negative absorption band was referred to the transition Fe 2O 3 and Fe 3O 4 formation at high temperature γ -irradiation. SQUID magnetometry of the glass with 2–3 wt% Fe 2O 3 revealed isolated iron ions and Fe 2O 3 particles with small hysteresis loop.
