Electroresistance, magnetocapacitance and magnetotransport properties of La0.55Ca0.45MnO3/BaTiO3 composite

Structural and Magnetoelectric Behavior of Lanthanum Manganite‐Based Multiferroic Heterostructures

“…However, ferroelectric and ferromagnetic Curie temperatures of the composite phases are equal to those of the pure components. This is typical for lanthanum manganite‐based ME composites, as pointed out by many refereed publications …”

“…An interest in lanthanum manganite‐based composite materials began to be taken quite recently, and the studies on this subject are relatively few in number . The majority of them are devoted to the properties of the systems with barium titanate as a piezoelectric phase . Traditional solid‐state methods as well as wet chemistry techniques are used to prepare the composites.…”

“…[5][6][7][8][9][10][11][12][13][14][15] The majority of them are devoted to the properties of the systems with barium titanate as a piezoelectric phase. [5][6][7][8][9][10][11][12][13][14] Traditional solid-state methods [5][6][7][8][9][10][11] as well as wet chemistry techniques 12,13 are used to prepare the composites. Sintering temperatures for ME ceramics vary from 900 7,9,12 up to 1200°C.…”

“…Sintering temperatures for ME ceramics vary from 900 7,9,12 up to 1200°C. 5,13 X-ray powder diffraction (XRD) data [5][6][7][8][9] and the absence of changes in Curie temperature and coercitive field strength of the manganite phase 8 are considered to indicate that there is no interfacial interaction between the components even in doping level. However, analyzing the XRD patterns given in the number of papers, one can see a shift of the diffraction peaks of the composites relative to the peaks of the pure phases.…”

Magnetic properties of (La 0.7 Sr 0.3 MnO 3 ) x (CaCu 3 Ti 4 O 12 ) 1−x nanostructured composites

“…Based on investigations of the magnetic properties of ferromagnet + ferroelectric-type composite (La 0.55 Ca 0.45 MnO 3 ) 0.8 (BaTiO 3 ) 0.2 it was shown that pure La 0.55 Ca 0.45 MnO 3 and the composite sample show magnetoresistance effect, while the high electroresistance effect was found only in the composite [8]. LSMO-based composites, in which the glass-forming additive Sb 2 O 3 is used as the second phase, demonstrated at room temperature the negative isotropic magnetoresistance, which increases with an increase in the magnetic field [9].…”
