Phase transition and polar cluster behavior above Curie temperature in ferroelectric BaTiZrO
Oktay Aktas, Francisco Javier Romero, Zhengwang He +5
We study the phase transition behavior of the ferroelectric BaTiZrO in the paraelectric region. The temperature dependencies of thermal, polar, elastic and diel…
Spin glass behavior in amorphous Cr2Ge2Te6 phase-change alloy
Xiaozhe Wang, Suyang Sun, Jiang-Jing Wang +8
The layered crystal structure of Cr2Ge2Te6 shows ferromagnetic ordering at the two-dimensional limit, which holds promise for spintronic applications. However, external voltage pul…
Elastic precursor effects during the BaSrTiO ferroelastic phase transitions
Francesco Cordero, Francesco Trequattrini, Paulo Sergio da Silva +3
Elastic softening in the paraelastic phases of BaSrTiO is largest near the transition temperatures and decreases on heating smoothly over extended temperature r…
Piezoelectricity in Nominally Centrosymmetric Phases
Oktay Aktas, Moussa Kangama, Gan Linyu +4
Compound phases often display properties that are symmetry-forbidden relative to their nominal, average crystallographic symmetry, even if extrinsic reasons (defects, strain, imper…
Control of surface potential at polar domain walls in a nonpolar oxide
G. F. Nataf, M. Guennou, J. Kreisel +8
Ferroic domain walls could play an important role in microelectronics, given their nanometric size and often distinct functional properties. Until now, devices and device concepts…
Raman scattering study of delafossite magnetoelectric multiferroic compounds: CuFeO2 and CuCrO2
O. Aktas, K. D. Truong, T. Otani +4
Ultrasonic velocity measurements on the magnetoelectric multiferroic compound CuFeO2 reveal that the antiferromagnetic transition observed at TN1 = 14 K might be induced by an R-3m…
Landau model for the elastic properties of the ferroelastic crystal Rb4LiH3(SO4)4
G. Quirion, W. Wu, J. Rideout +1
We report a detailed investigation of the elastic properties of Rb4LiH3(SO4)4 measured as a function of temperature and pressure. Rb4LiH3(SO4)4 is known to show a 4 - 2 ferroelasti…
