摘要：
Recent progress in exploring and developing new microwave absorbing materials is highlighted. In this paper, we reported on microwave electromagnetic properties of the novel quaternary ferrite La-substituted Ba12Fe28Ti15O84 prepared via a modified sol-gel method. A systematic study was conducted to identify the effects of La substitution on structure, conductive, dielectric, magnetic and microwave absorbing properties. The modified samples had a monoclinic crystal structure and exhibited dense plate-like grains. The introduction of La into Ba12Fe28Ti15O84 had a remarked influence on conductive behavior, dielectric and magnetic properties and in turn provided the tunable microwave electromagnetic properties. A significant enhancement of reflection loss (RL) was observed for the Ba12-xLaxFe28-Ti15O84 (x = 3) sample, showing a broadened absorption bandwidth (RL < -10 dB) covering the nearly X-band. In addition, microwave absorption mechanism of the doped ceramics was discussed. (C) 2019 Elsevier B.V. All rights reserved.
