Magnetic materials for magnetoelectric coupling: An unexpected journey

Abstract

Magnetic materials for magnetoelectric coupling are reported. After an introduction of magnetoelectric effect and materials, an historical on the main developments in this field are presented. Then, the main concepts related to multiferroic and magnetoelectric materials are introduced, together with the description of the main types of 2 magnetoelectric materials and structures. Finally, the magnetic materials used the development of magnetoelectric composites are presented and discussed, highlighting their main physico-chemical characteristics and processing methods. In this way, a complete account on concepts, materials and methods is presented in this strongly evolving research field, with strong application potential in the areas of sensors and actuators, among others.

Magnetic phenomena in equiatomic ternary rare earth compounds

“…Magnetic materials play a vital role in numerous daily life applications ranging from transportation to medicine and electronics, to energy harvesting and household appliances [1][2][3][4][5]. Various magnetic materials have been investigated to explore their magnetic properties and application potentials.…”

Weight Loss during Calcination and Sintering Process of Na0.5Bi0.5TiO3–Bi1/2(Mg2/3Nb1/3)O3 Composite Lead-Free Piezoelectric Ceramics

“…Moreover, the European Union (EU) passed legislation on Restriction of Hazardous Substances (RoHS), Waste from Electrical and Electronic Equipment (WEEE), and End of Life Vehicles (ELV), propelling scientists to take out poisonous substances from electrical and electronic devices to lessen their effect on the surroundings and wellbeing of people [6]. Sodium bismuth titanate (Na 0.5 Bi 0.5 TiO 3 denoted as NBT) is one of the emerging lead-free ceramics, and it was discovered in 1960 [7,8]. It has a distorted perovskite structure (ABO 3 ) with rhombohedral R3c symmetry at room temperature (RT).…”
