The long spin-relaxation time (τs) toward the large transport distance of spin current (SC) is desirable for practical applications of spintronic devices because spatially and temporally large spin coherence makes spin manipulation easier. Here, we

The relativistic effect on electromagnetic forces yields two types of forces which depend on the velocity of the relevant particles: (i) the usual Lorentz force exerted on a moving charged particle and (ii) the apparent Lorentz force exerted on a mov

Spin-charge (SC) coupling is crucial in spintronics and the coupling mechanisms can be classified into bulk characteristic via spin-orbit interaction (SOI) or the interfacial characteristic provided by a junction formed by magnetic and nonmagnetic co

Background: In this paper, we report on the topics of one-dimensional (1D) and two-dimensional (2D) functional materials. Single-Walled Carbon Nanotubes (SWCNTs) are seamless hollow cylinders made of hexagonal lattice graphite sheets. The SWCNTs have

To decrease the temperature at which metallic yttrium (Y) reacts with H2 to form the semiconductor trihydride phase, we employed Pt capping layers as catalysts, and compared the result with those obtained when employing Pd, Ni, or their co-capping la

The concept of contingency is very much debated. In this paper, I’ll offer a novel interpretation of it in Dharmakīrti’s ontology, focusing on his treatment and understanding of vināśa (translation: perishing) which is, according to Dharmakīr

This study addressed Hall effect measurements in the nonstoichiometric α-phase ytterbium dihydride (α-YbH2±δ) and β-phase ytterbium trihydride (β-YbH3−δ) films. We have prepared orthorhombic α-YbH2.05 and cubic β-YbH2.7 polycrystalline fil

We develop a theory describing spatiotemporal behavior of spin transport in two-band metals by postulating a spin–exchange interaction between electrons and holes. Starting with the semiclassical Boltzmann equation, we derive a system of coupled di
