Double excitations, which are dominated by a Slater determinant with both electrons in the highest occupied molecular orbital promoted to lowest unoccupied orbital(s), pose significant challenges for low-cost electronic structure calculations based on density-functional theory (DFT). Here, we demonstrate that recent advances ensemble DFT [Gould et al., Phys. Rev. Lett. 125, 233001 (2020)], exte...

Spin torque oscillators (STOs) are currently of great interest due to its wide tunable frequencies, low energy consumption and high quality factors compared with traditional oscillators. Here, we report the characteristics of the nanocontact-(NC-)STO in the presence of interfacial Dzyaloshinskii-Moriya interaction (DMI), using micromagnetic simulations. We find that the DMI can decrease the STO...

The U.S. Army Tank-Automotive Research, Development and Engineering Center (TARDEC) recently completed a Science and Technology Objective (STO) to develop and demonstrate a compact on-board smart sensor system for monitoring the operational condition of in-service diesel engine oils. The goal of such technologies is to reduce or eliminate the Army’s dependence on traditional oil analysis method...

and Applied Analysis 3 At resonance levels, ur should be arbitrary, and then we are deducing a nonlinear equation g ur−1 · · ·u0, φ · · · 0. If the equation f implies g, then the compatibility condition is unconditionally satisfied. An equation for which these three steps can be carried out consistently and unambiguously passes the Painlevé test. Equation 1.3 is called the truncated Painlevé ex...

Since the discovery of colossal magnetoresistance in manganites, there is a high interest in the fabrication of magnetic tunnel junctions made with all-oxide ferromagnetic electrodes and barrier. (001)-oriented La2/3Ca1/3MnO3 (LCMO) and SrTiO3 (STO) films are the most investigated materials as ferromagnetic electrode and tunnel barrier, respectively. The usefulness of these oxides for the appli...

In our previous report, we demonstrated the growth of high-quality epitaxial Co-doped (Ba-122) thin films using single crystalline (STO) templates on (LSAT) substrates with pulsed laser deposition (PLD). Here, we report the dependence of the structural and superconducting properties of Ba-122 thin films on STO templates that were 2-150 unit cell (u.c.) thick. We obtained genuine epitaxial thin ...

We show a detailed magneto-optical Kerr study at room temperature of well characterized epitaxial La0.7Sr0.3MnO3 (LSMO) thin films grown onto (110) and (11̄8) SrTiO3 substrates. The films present a well-defined uniaxial (two-fold) magnetic anisotropy ascribed to substrate-induced anisotropy. In particular, the in-plane uniaxial anisotropy in the(110)-oriented LSMO films originates from the exist...

$EVWUDFWW This paper deals with the STO lexicon, the most comprehensive computational lexicon of Danish developed for NLP/HLT applications, which is now ready for use. Danish was one of the 12 EU-languages participating in the LE-PAROLE and SIMPLE projects; therefore it was obvious to continue this work building on our experience obtained from these projects. The material for Danish produced wi...

Undoped strontium titanate, SrTiO3 (STO), is a widely studied ceramic material with a huge dielectric constant ε, ranging from 300 at room temperature up to 5000 at T = 80 K[1]. The large values of ε are a macroscopic signature that the internal charges are easily displaced by an external electric field, while the material remains an excellent insulator. These properties have made STO an intere...

The bulk photovoltaic effect is a long-known but poorly understood phenomenon. Recently, however, the multiferroic bismuth ferrite has been observed to produce strong photovoltaic response to visible light, suggesting that the effect has been underexploited. Here we present three polar oxides in the LiNbO3 structure that we predict to have band gaps in the 1–2 eV range and very high bulk photov...
