Pressure-mediated structural transitions in bulk EuTiO3

Title: Pressure-mediated structural transitions in bulk ${EuTiO}_{3}$

Abstract

The high pressure structural phase diagram of EuTiO ₃ is revisited by means of single crystal x-ray diffraction at pressures below 30GPa. We report a transition at about 3GPa with a surprisingly small lattice distortion. At 23GPa we have detected a yet unknown transition into a new orthorhombic phase (space group Ibam). Combining our observations on structures obtained on single crystals and polycrystalline samples with complementary methods, such as electrical resistivity and nuclear forward scattering of synchrotron radiation measured on polycrystalline samples, we address issues relevant to chemistry and disorder.

Crystal field levels and magnetic anisotropy in the kagome compounds ${Nd}_{3} {Sb}_{3} {Mg}_{2} O_{14}$ , ${Nd}_{3} {Sb}_{3} {Zn}_{2} O_{14}$ , and $\Pr_{3} {Sb}_{3} {Mg}_{2} O_{14}$

Journal Article Scheie, A. ; Sanders, M. ; Krizan, J. ; ... - Physical Review B

Here, we report the crystal field levels of several newly discovered rare-earth kagome compounds: Nd ₃Sb ₃Mg ₂O ₁₄, Nd ₃Sb ₃Zn ₂O ₁₄, and Pr ₃Sb ₃Mg ₂O ₁₄. We determine the crystal electric field (CEF) Hamiltonian by fitting to neutron scattering data using a point charge Hamiltonian as an intermediate fitting step. The fitted Hamiltonians accurately reproduce bulk susceptibility measurements, and the results indicate easy-axis ground-state doublets for Nd ₃Sb ₃Mg ₂O ₁₄ and Nd ₃Sb ₃Zn ₂O ₁₄ and a singlet ground state for Pr ₃Sb ₃Mg ₂O ₁₄. These results provide the groundwork for future investigationsmore »« less

Superconducting $B i_{2} Te$ : Pressure-induced universality in the ${(B i_{2})}_{m} {(B i_{2} T e_{3})}_{n}$ series

Journal Article Stillwell, Ryan L. ; Jenei, Zsolt ; Weir, Samuel T. ; ... - Physical Review B

Using high-pressure magnetotransport techniques we have discovered superconductivity in Bi2Te, a member of the infinitely adaptive (Bi2)n(Bi2Te3)m series, whose end members, Bi and Bi2Te3, can be tuned to display topological surface states or superconductivity. Bi2Te has a maximum Tc= 8.6 K at P= 14.5 GPa and goes through multiple high pressure phase transitions, ultimately collapsing into a bcc structure that suggests a universal behavior across the series. High-pressure magnetoresistance and Hall measurements suggest a semi-metal to metal transition near 5.4 GPa, which accompanies the hexagonal to intermediate phase transition seen via x-ray diffraction measurements. In addition, the linearity of Hc2(T)more »« less

Field-induced polarization rotation and phase transitions in $0.70 Pb (M g_{1 / 3} N b_{2 / 3}) O_{3} - 0.30 PbTi O_{3}$ piezoceramics observed by in situ high-energy x-ray scattering

Journal Article Hou, Dong ; Usher, Tedi -Marie ; Fulanovic, Lovro ; ... - Physical Review B

Changes to the crystal structure of 0.70Pb(Mg _1/3Nb _2/3)O ₃–0.30PbTiO ₃ (PMN-0.30PT) piezoceramic under application of electric fields at the long-range and local scale are revealed by in situ high-energy x-ray diffraction (XRD) and pair-distribution function (PDF) analyses, respectively. The crystal structure of unpoled samples is identified as monoclinic Cm at both the long-range and local scale. In situ XRD results suggest that field-induced polarization rotation and phase transitions occur at specific field strengths. A polarization rotation pathway is proposed based on the Bragg-peak behaviors and the Le Bail fitting results of the in situ XRD patterns. The PDF resultsmore »« less

Anisotropic $H_{c 2}$ , thermodynamic and transport measurements, and pressure dependence of $T_{c}$ in $K_{2} {Cr}_{3} {As}_{3}$ single crystals

Journal Article Kong, Tai ; Bud'ko, Sergey L. ; Canfield, Paul C. - Physical Review. B, Condensed Matter and Materials Physics

We present a detailed study of single crystalline K ₂Cr ₃As ₃ and analyze its thermodynamic and transport properties, anisotropic H _c2(T), and initial pressure dependence of T _c. In zero field, the temperature-dependent resistivity is metallic. Deviation from a linear temperature dependence is evident below 100 K and a T ³ dependence is roughly followed from just above T _c (~10K) to ~40K. Anisotropic H _c2(T) data were measured up to 140 kOe with field applied along and perpendicular to the rodlike crystals. For the applied field perpendicular to the rod, H _c2(T) is linear with a slope ~–70more »« less
