Room-temperature magnetoelectric coupling in single-phase BaTiO3-BiFeO3 system
In this paper, single-phase multiferroic ceramics of (1 x) BaTiO3 x BiFeO3 (BT x BFO) were synthesized by solid-solution method in the wide range of material composition (x1⁄4 0.025 – 1.0). The changes in crystal structure were confirmed via X-ray diffractions (XRD) and atomic pair distribution functions (PDFs). The room-temperature ME coupling was found to exhibit significant magnitude in the ...
متن کاملCanonical magnetic insulators with isotropic magnetoelectric coupling
We have performed a systematic representation-theory-based search for the simplest structures allowing isotropic magnetoelectric coupling. We find 30 such structures, all sharing a common pattern of atomic displacements in the direction of atomic magnetic moments. We focus on one of these 30 canonical structures and find that it is generically realized in a class of fractionally substituted pyr...
متن کاملMagnetic ordering induced giant optical property change in tetragonal BiFeO3
Magnetic ordering could have significant influence on band structures, spin-dependent transport, and other important properties of materials. Its measurement, especially for the case of antiferromagnetic (AFM) ordering, however, is generally difficult to be achieved. Here we demonstrate the feasibility of magnetic ordering detection using a noncontact and nondestructive optical method. Taking t...
متن کاملIncommensurate superlattice ordering in priderite
The mineral priderite has been examined by electron microprobe analysis and electron diffraction. The composition was approximately (Ko.97Bao.aa)(FeH7 Ti6.60Mg0.23)O16, which is in line with the observed superlattice periodicity of m = 5.88, there being intergrowths of rn = 5 and m = 6 superstructures. A surprisingly high degree of lateral correlation between tunnel cations was noted. RECENTLY ...
متن کاملCommensurate-incommensurate magnetic phase transition in magnetoelectric single crystal LiNiPO(4).
Neutron scattering studies of single crystal LiNiPO4 reveal a spontaneous first-order commensurate-incommensurate magnetic phase transition. Short- and long-range incommensurate phases are intermediate between the high temperature paramagnetic and the low temperature antiferromagnetic phases. The modulated structure has a predominant antiferromagnetic component, giving rise to satellite peaks i...
