Stabilization of layered perovskite structures via strontium substitution in CaTiO revealed via elemental mapping
Kosuke Kurushima, Hiroshi Nakajima, Shinya Mine +5
Extensive studies have been performed on layered compounds, ranging from layered cuprates to van der Waals materials with critical issues of intergrowths and stacking faults. Howev…
Charged domain boundaries stabilized by translational symmetry breaking in the hybrid improper ferroelectric CaSrTiO
Hiroshi Nakajima, Kosuke Kurushima, Shinya Mine +5
Charged domain walls and boundaries in ferroelectric materials display distinct phenomena, such as an increased conductivity due to the accumulation of bound charges. Here, we repo…
Infrared nano-spectroscopy of ferroelastic domain walls in hybrid improper ferroelectric CaTiO
K. A. Smith, E. A. Nowadnick, S. Fan +14
Ferroic materials are well known to exhibit heterogeneity in the form of domain walls. Understanding the properties of these boundaries is crucial for controlling functionality wit…
Mapping the structural transitions controlled by the trilinear coupling in Ca3-xSrxTi2O7
Marie Kratochvilova, Fei-Ting Huang, Maria-Teresa Fernandez Diaz +7
We present the results of the high-temperature neutron and x-ray diffraction experiments on the Ca3-xSrxTi2O7 (x = 0.5, 0.8, 0.85, 0.9) compounds. The ferro- to paraelectric transi…
Nature of the Structural Symmetries Associated with Hybrid Improper Ferroelectricity in Ca3X2O7
S. Liu, H. Zhang, S. Ghose +8
In hybrid improper ferroelectric systems, polarization arises from the onset of successive nonpolar lattice modes. In this work, measurements and modeling were performed to determi…
Magnetic properties of double perovskite CoIrO ( = Eu, Tb, Ho): hetero-tri-spin -- systems
Xiaxin Ding, Bin Gao, Elizabeth Krenkel +4
The field of double perovskites is now advancing to three magnetic elements on the A, B and B sites. A series of iridium-based double perovskite compounds, CoIrO (…
