Materials Relevant to Realizing a Field-Effect Transistor based on Spin-Orbit Torques
Phillip Dang, Zexuan Zhang, Joseph Casamento +6
Spin-orbit torque is a promising mechanism for writing magnetic memories, while field-effect transistors are the gold-standard device for logic operation. The spin-orbit torque fie…
Growth of CuFeO Single Crystals by the Optical Floating-Zone Technique
Nora Wolff, Tobias Schwaigert, Dietmar Siche +2
CuFeO single crystals up to 50 mm in length and up to 10 mm in diameter were grown by the optical floating-zone method. Stoichiometric polycrystalline rods with a diameter of 6…
Non-thermal fluence threshold for femtosecond pulsed x-ray radiation damage in perovskite complex oxide epitaxial heterostructures
Hyeon Jun Lee, Youngjun Ahn, Samuel D. Marks +13
Intense hard x-ray pulses from a free-electron laser induce irreversible structural damage in a perovskite oxide epitaxial heterostructure when pulse fluences exceed a threshold va…
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…
Thermal Expansion in Insulating Solids From First Principles
Ethan T. Ritz, Sabrina J. Li, Nicole A. Benedek
In this Tutorial, we describe the use of the quasiharmonic approximation and first-principles density functional theory (DFT) to calculate and analyze the thermal expansion of insu…
Effect of strain on magnetic and orbital ordering of LaSrCrO/LaSrMnO heterostructures
Sanaz Koohfar, Alexandru B. Georgescu, Ingrid Hallsteinsen +4
We investigate the effect of strain and film thickness on the orbital and magnetic properties of LaSrCrO (LSCO)/LaSrMnO (LSMO) heterostructures using bulk magnetometry, sof…
