Non-collinear and strongly asymmetric polar moments at back-gated SrTiO3 interfaces
Fryderyk Lyzwa, Yurii G. Pashkevich, Premysl Marsik +15
The highly mobile electrons at the interface of SrTiO3 with other oxide insulators, such as LaAlO3 or AlOx, are of great current interest. A vertical gate voltage allows controllin…
Bifurcations observed in the spectra of coupled electron-phonon modes in multiferroic subjected to a magnetic field
K. N. Boldyrev, T. N. Stanislavchuk, A. A. Sirenko +3
We report on bifurcations effect mediated by the electron-phonon coupling in a concentrated rare-earth-containing antiferromagnet, observed in the spectra of coupled -electron-…
Novel Layered Iridate Ba7Ir3O13+δ Thin Films with Colossal Permittivity
Ludi Miao, Yan Xin, Jinyu Liu +7
Ba7Ir3O13+δ in thin film form is discovered. These films are characterized by colossal permittivity (CP) ~104 at room temperature, attributable to the colossal internal barrier lay…
Splitting of a nondegenerate phonon mode in PrFe3(BO3)4: 4f crystal-field level between TO and LO phonon frequencies
K. N. Boldyrev, T. N. Stanislavchuk, A. A. Sirenko +2
A new effect originating from the crystal-field-excitation - phonon coupling was observed (in the far infrared spectra of a multiferroic PrFe3(BO3)4). The reststrahlen band corresp…
High carrier mobility in transparent Ba1-xLaxSnO3 crystals with a wide band gap
X. Luo, Y. S. Oh, A. Sirenko +4
We discovered that perovskite (Ba,La)SnO3 can have excellent carrier mobility even though its band gap is large. The Hall mobility of Ba0.98La0.02SnO3 crystals with the n-type carr…
Epitaxial checkerboard arrangement of nanorods in ZnMnGaO4 films studied by x-ray diffraction
S. M. O'Malley, P. L. Bonanno, K. H. Ahn +4
The intriguing nano-structural properties of a ZnMnGaO4 film epitaxially grown on MgO (001) substrate have been investigated using synchrotron radiation-based x-ray diffraction. Th…
