Author(s): Michael Widom The AlCrTiV high entropy alloy undergoes an order-disorder transition from body-centered cubic (Strukturbericht A2) at high temperatures to the CsCl structure (B2) at intermediate temperatures. We model this transition using first principles Monte Carlo/molecular dynamics simulations. Simulation res… [Phys. Rev. Materials 8, 093603] Published Tue Sep 10, 2024

Aczel Polycrystalline and single-crystal samples of the insulating Shastry-Sutherland compound ${\mathrm{Er}}_{2}{\mathrm{Be}}_{2}{\mathrm{SiO}}_{7}$ were synthesized via a solid-state reaction and the floating zone method, respectively. The crystal structure, Er single-ion anisotropy, zero-field magnetic...

Tsymbal, and Tamalika Banerjee Magnetic tunnel junctions (MTJs) that are comprised of epitaxially grown complex oxides offer a versatile platform to control the symmetry of tunneling states and tailor magnetic anisotropy useful for practical applications. This work employs thin films of ${\mathrm{SrTiO}}_{3}$ as an insulating bar… [Phys...

Author(s): Hua-Xun Li, Hao Jiang, Yi-Qiang Lin, Jia-Xin Li, Shi-Jie Song, Qin-Qing Zhu, Zhi Ren, and Guang-Han Cao We report a layered transition-metal-ordered oxypnictide ${\mathrm{Sr}}_{2}{\mathrm{CrCoAsO}}_{3}$. The new material was synthesized by solid-state reactions under vacuum. It has an intergrowth structure with a perovskite-like ${\mathrm{Sr}}_{3}{\mathrm{Cr}}_{2}{\mathrm{O}}_{6}$ unit and ${\mathrm{T… [Phys. Rev. Materials 8, 094405...

Author(s): Sijia Tu, Jinsong Zhang, Zefeng Lin, Beiyi Zhu, Qihong Chen, Jie Yuan, and Kui Jin We report a systematic study of the thickness effect on the superconductivity of overdoped $\mathrm{L}{\mathrm{a}}_{2−x}\mathrm{C}{\mathrm{e}}_{x}\mathrm{Cu}{\mathrm{O}}_{4−δ}$ films. As the film thickness decreases, a recurrence of superconductivity is observed in the $x=0.19$ film, while this dopi… [Phys. Rev. Materials 8, 094801] Published Mon Sep...

Author(s): A. Zafar, A. M. Milinda Abeykoon, and V. Petkov The structural mechanism of the magnetic phase transitions in ${\mathrm{FeTiO}}_{3}$ ilmenite, including the paramagnetic (PM) to antiferromagnetic (AFM) transition induced by reducing temperature in zero magnetic field and the AFM to ferromagnetic (FM) transition induced by applying strong magnetic… [Phys.

Author(s): Muskan Sande, Joydev Khatua, Youngsu Choi, and Kwang-Yong Choi The site-selective substitution of diamagnetic ${d}^{10}/{d}^{0}$ cations offers an efficient way to fine-tune magnetic characteristics by controlling orbital hybridization and superexchange pathways. Herein, we explore the tunability of magnetic properties in coupled spin-ladder compounds $\mathrm{… [Phys. Rev. Materials 8, 094404] Published Fri Sep 06, 2024
