Optimizing electro-strain <i>via</i> manipulating the oxygen octahedral structure in BF–BT-based ceramics
Bing Li, Junfei Guo, Shizhao Zhong, Ting Zheng, Jiagang Wu
Abstract
The origin of improved electrostrain property is the synergic contributions including symmetrical O–O and Fe–O bond lengths and a certain degree of oxygen octahedral tilt, as well as miniaturized maze-like domain structure.
