Unconventional Multiferroicity in Cupric Oxide
Pierre Toledano, Naemi Leo, Dmitry D. Khalyavin +4
The magnetic phase transitions reported below 230 K in cupric oxide are analyzed theoretically at the macroscopic and microscopic levels. The incommensurate multiferroic and lock-i…
Spontaneous toroidic effects in Ba2CoGe2O7
Pierre Toledano, Dmitry D. Khalyavin, Laurent C. Chapon
The unusual magnetoelectric effects observed in the multiferroic phase arising below TN=6.7K in Ba2CoGe2O7 (BCG) are related to the spontaneous toroidal moment existing in this com…
Spin-state ordering and magnetic structures in YBaCo2O5.5/5.44
D. D. Khalyavin, D. N. Argyriou, U. Amann +2
The antiferromagnetic - ferromagnetic phase transition in YBaCo2O5.50 and YBaCo2O5.44 cobaltites with different types of oxygen-ion ordering in the [YO0.5/0.44] layers has been stu…
Singularities of Magnetic and Elastic Characteristics of La2/3Ba1/3MnO3: Analysis of Martensitic Kinetics
E. L. Fertman, A. B. Beznosov, V. A. Desnenko +3
A coordinated temperature behavior of magnetic susceptibility and internal friction has been observed in the La2/3Ba1/3MnO3 manganite in the temperature region of the crystal phase…
Structural phase separation in La2/3Ba1/3MnO3: macroscopic and microscopic aspects
A. B. Beznosov, E. L. Fertman, P. P. Pal-Val +4
The structural phase transformation in the La2/3Ba1/3MnO3 perovskite manganite was studied by ultrasound, neutron diffraction and electron microscopy techniques. Minima of the velo…
Structure-dependent microwave dielectric properties of (1-x)La(Mg1/2Ti1/2)O3 - xLa2/3TiO3 ceramics
A. N. Salak, D. D. Khalyavin, P. Q. Mantas +2
Structure and dielectric characterization were performed on the (1-x)La(Mg1/2Ti1/2)O3 - xLa2/3TiO3 perovskite ceramics with the actual composition 0<=x<=0.52. The sequence of struc…
