Observation of linear magnetoelectric effect in a Dirac magnon antiferromagnet CuTeO
Aga Shahee, Kyongjun Yoo, B. Koteswararao +2
CuTeO, a three-dimensional antiferromagnet forming a unique spin-web lattice of spin-1/2 Cu2+ ions below the Neel temperature T = 62 K, has recently been found to exhib…
Phase transition between two different orientations of the Q phase in the NaNbO thin film
A. V. Pavlenko, D. V. Stryukov, M. V. Vladimirov +8
Temperature evolution of dielectric response, atomic structure, and lattice dynamics in thin film of sodium niobate in the epitaxial NaNbO/SrRuO/(001)MgO heterostructure is…
Predicting the Structural, Electronic and Magnetic Properties of Few Atomic-layer Polar Perovskite
Shaowen Xu, Fanhao Jia, Shunbo Hu +7
Density functional theory (DFT) calculations are performed to predict the structural, electronic and magnetic properties of electrically neutral or charged few-atomic-layer (AL) ox…
Linear magnetoelectric effect in the antiferromagnetic Sm2BaCuO5
Premakumar Yanda, N. V. Ter-Oganessian, A. Sundaresan
We report the discovery of linear magnetoelectric effect in the well-known green phase compound, Sm2BaCuO5, which crystallizes in the centrosymmetric orthorhombic (Pnma) structure.…
Magnetic and magnetoelectric properties of FeF ( = Ca, Sr) spin-chain compounds
N. V. Ter-Oganessian, S. A. Guda, V. P. Sakhnenko +1
Fluorides in general are characterized by big variety of crystal structures, whereas those containing transition metals also often show sizable magnetic properties. The tendency of…
Effect of pressure on the order-disorder phase transitions of -cations in O perovskites
N. V. Ter-Oganessian, V. P. Sakhnenko
Perovskite-like oxides O may experience different ordering degrees of -cations, that can be varied by suitable synthesis conditions or post-synthesis tre…
Multiferroic rust: magnetoelectric effect in göthite, -FeOOH
N. V. Ter-Oganessian, A. A. Guda, V. P. Sakhnenko
By means of symmetry analysis, density functional theory calculations, and Monte Carlo simulations we show that goethite, -FeOOH, is a linear magnetoelectric below its Néel temp…
Linear magnetoelectric effect as a signature of long-range collinear antiferromagnetic ordering in the frustrated spinel CoAl2O4
Somnath Ghara, N. V. Ter-Oganessian, A. Sundaresan
The ground state of the frustrated A-site magnetic spinel CoAl2O4 has been a controversial issue whether it is a collinear antiferromagnetic ordering or a spiral spin - liquid stat…
Electric polarization of magnetic domain walls in magnetoelectrics
I. P. Lobzenko, P. P. Goncharov, N. V. Ter-Oganessian
Two prominent magnetoelectrics MnWO and CuO possess low-temperature commensurate paraelectric magnetically ordered phase. Here using Monte Carlo simulations we show that the wa…
Cation-ordered AABX magnetic spinels as magnetoelectrics
N. V. Ter-Oganessian
We show that 1:1 ordering of A and A cations in AABX magnetic spinels results in appearance of magnetoelectric properties. Possible value of magne…
Interpretation of magnetoelectric phase states using the praphase concept and exchange symmetry
N. V. Ter-Oganessian, V. P. Sakhnenko
The majority of magnetoelectric crystals show complex temperature-magnetic field or temperature-pressure phase diagrams with alternating antiferromagnetic incommensurate, magnetoel…
Magnetoelectric effect due to local noncentrosymmetry
V. P. Sakhnenko, N. V. Ter-Oganessian
Magnetoelectrics often possess ions located in noncentrosymmetric surroundings. Based on this fact we suggest a microscopic model of magnetoelectric interaction and show that the s…
