Magnetization and room temperature Mössabuer studies of 50Fe2O3-50SiO2 and 90Fe2O3-10SiO2 ceramic fibers processed by laser floating zone method

Impact of the pulling rate on the redox state and magnetic domains of Fe-Si-O glass ceramic processed by LFZ method

“…Up to now, various techniques including chemical methods such as sol-gel, co-precipitation [1,3] and/or high-temperature processing methods like laser ablation, melt-quenching and laser processing [5,7] have been used to produce iron oxide doped glass-ceramics. Among them, laser floating zone (LFZ) method was found as a powerful processing technique enabling to prepare not only the glass-ceramic materials [7] but also high-quality single crystals [18][19][20], eutectic J o u r n a l P r e -p r o o f structures [3,[21][22][23] and highly oriented polycrystalline materials [23][24][25][26]. Moreover, by providing conditions for a self-supported molten zone, the LFZ method has merit over other high-temperature synthesis approaches to avoid contamination and impurities resulted from high-temperature interaction with crucibles or other materials [27].…”
