Effect of nucleating agents on magnetic properties and relaxation in magnetite-based glass-ceramics prepared by controlled crystallization of borosilicate glasses

Sandu V., Cimpoiasu E., Greculeasa S., Kuncser A., Kuncser V., Nicolescu M.S., Kuncser A., Kuncser V., U.S. Naval Academy, US

We investigated the specific magnetic structure and magnetic relaxation phenomena in magnetite nano-entities grown in a glassy matrix by controlled crystallization of Fe-containing borosilicate and boroaluminosilicate glasses in the presence of two types of nucleating [...]

Nanoscale Maghemite Iron Oxide Powders Prepared by Laser Pyrolysis

Morjan I., Dumitrache F., Alexandrescu R., Birjega R., Voicu I., Gavrila L., Soare I., Filotti G., Kuncser V., Ciupina V., National Institute for Lasers, Plasma and Radiation Physics, RO

Nano-sized maghemite particles (usually less than 15 nm diameter) have been directly synthesized by the laser induced pyrolysis of iron pentacarbonyl vapors. Ethylene was used as sensitizer of the induced reaction. By the controlled use [...]
