Anisotropy in antiferromagnets [PDF]

Journal of Applied Physics, 2020
Due to the advent of antiferromagnetic (AF) spintronics, there is a burgeoning interest in AF materials for a wide range of potential and actual applications. Generally, AFs are characterized via the ordering at the Néel temperature (TN), but to have a stable AF configuration, it is necessary that the material has a sufficient level of anisotropy so as

Holographic spontaneous anisotropy [PDF]

Journal of High Energy Physics, 2020
Abstract We construct a family of holographic duals to anisotropic states in a strongly coupled gauge theory. On the field theory side the anisotropy is generated by giving a vacuum expectation value to a dimension three operator. We obtain our gravity duals by considering the geometry corresponding to the intersection of D3- and ...

Is there anisotropy in structural bias? [PDF]

Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2021
Structural Bias (SB) is an important type of algorithmic deficiency within iterative optimisation heuristics. However, methods for detecting structural bias have not yet fully matured, and recent studies have uncovered many interesting questions. One of these is the question of how structural bias can be related to anisotropy. Intuitively, an algorithm

First-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Preliminary Maps and Basic Results [PDF]

, 2003
We present full-sky microwave maps in five frequency bands (23-94 GHz) from the Wilkinson Microwave Anisotropy Probe (WMAP) first-year sky survey. Calibration errors are less than 0.5%, and the low systematic error level is well specified.

Effect of in-situ synthesized TiB2 on microstructure and mechanical property of Al/TiB2-SiC interpenetrating phase composites

Journal of Asian Ceramic Societies, 2022
Al/TiB2-SiC composites were prepared based on TiB2-SiC porous ceramic preforms. The advantages of this work were characterized by the in-situ synthesized TiB2 in porous ceramic preforms which directly formed interconnected pores as well as TiB2-SiC ...

Burning question: Are there sustainable strategies to prevent microbial metal corrosion?

Microbial Biotechnology, 2023
The global economic burden of microbial corrosion of metals is enormous. Microbial corrosion of iron‐containing metals is most extensive under anaerobic conditions.

Anisotropy in MgB2 [PDF]

Brazilian Journal of Physics, 2003
The first direct measurement of an anisotropic superconducting property in MgB2 was achieved for the bulk nucleation field Hc2, in a sample of aligned crystallites. It was found a ratio g(T) = Habc2/ Hcc2= 1.6 - 1.9, for T varying from 32 K to 26K, between H applied parallel to the ab plane, and along the c direction.

Charge-Transfer Process in Surface-Enhanced Raman Scattering Based on Energy Level Locations of Rare-Earth Nd³⁺-Doped TiO₂ Nanoparticles

Nanomaterials, 2021
Surface-enhanced Raman scattering (SERS) for semiconductor nanomaterial systems is limited due to weak Raman signal intensity and unclear charge-transfer (CT) processes for chemical enhancement.

Anisotropy and NMR spectroscopy [PDF]

Rendiconti Lincei. Scienze Fisiche e Naturali, 2020
Abstract In this paper, different aspects concerning anisotropy in Nuclear Magnetic Resonance (NMR) spectroscopy have been reviewed. In particular, the relevant theory has been presented, showing how anisotropy stems from the dependence of internal nuclear spin interactions on the molecular orientation with respect to the external magnetic field ...
