Antiferroelectrics and Magnetoresistance in La0.5Sr0.5Fe12O19 Multiferroic System

“…This results in a change in MR with greater energy efficiency and could make novel low-power tunable electronic devices more promising. Consequently, multiferroics consisting of ferromagnetic and ferroelectric orders were pushed forward to appear in front of us due to the capability of voltage straightforward switching magnetization through magnetoelectric (ME) coupling effect [ 3 , 4 , 5 ], which brings us a variety of unprecedented physical phenomena [ 6 , 7 , 8 ].…”

“…Multiferroic materials can be used to realize a new generation of multifunctional devices which integrate ferroelectricity and magnetism, that is, new magnetoelectric sensing devices, spin electronic devices, high-performance information storage devices [ 4 , 9 ]. The multiferroic material with the ME coupling effect uses voltage rather than current to regulate the magnetization direction and minimizes joule heat dissipation.…”

“…The multiferroic material with the ME coupling effect uses voltage rather than current to regulate the magnetization direction and minimizes joule heat dissipation. It can fundamentally solve the problem of high energy consumption of storage devices [ 4 ]. The conventional multiferroic feature consists of ferroelectrics (FM) and antiferromagnetism (AFM) or ferromagnetism (FM) [ 1 , 4 ].…”

Magnetic–dielectric bistabilities and magnetodielectric coupling effects in a new layered hybrid perovskite: (C6H5(CH2)4NH3)2[MnCl4]

“…Besides thermo-sensitive bistability, the field-controlled switchable physical properties, such as magnetodielectric effect (a typical magnetoelectric effect), have invoked significant research activities as well, for the goal of realizing potential applications in energy transformation devices and information storage systems. [22][23][24][25] In the past decades, the magnetodielectric effect has been widely investigated in oxide materials, and plenty of excellent fundamental researches and technologies have been achieved. [26][27][28] For example, large magnetodielectric effect in DyMnO 3 , 29 33 Simultaneously, tremendous progress has been made in organic-inorganic hybrid crystals, [34][35][36][37][38][39][40][41][42][43][44][45][46] such as giant and roomtemperature coupling effect in metal-formate framework and highly reproducible coupling effect in layered perovskites.…”
