Electric-field-controlled magnetism due to field-induced transition of Pna21/R3c in Bi1-xGdxFeO3 ceramics

Autor: Jing Chen, Nan Su, Xiao Li Zhu, Xiao Qiang Liu, Jin-Xing Zhang, Xiang Ming Chen

Publikováno v: Journal of Materiomics, Vol 7, Iss 5, Pp 967-975 (2021)

BiFeO3 has been recognized as one of the most important room-temperature single-phase multiferroic materials, but it still suffers from several drawbacks especially the weak magnetoelectric coupling. In the present work, the electric-field-controlled

Greatly enhanced permittivity in BaTiO3-epoxy dielectric composites with improved connectivity of ceramic phase

Autor: Meng Cao, Lei Li, Wen Bin Hong, Shu Ya Wu, Xiang Ming Chen

Publikováno v: Journal of Materiomics, Vol 7, Iss 1, Pp 1-7 (2021)

BaTiO3-epoxy dielectric composites were prepared by curing the liquid epoxy monomer that infiltrated into the partially-sintered BaTiO3 porous ceramics. The BaTiO3 volume fraction of the composites maintained around 58.6% with increasing the sinterin
