Lithium and Vanadium Intercalation into Bilayer V2Se2O: Ferrimagnetic–Ferroelastic Multiferroics and Anomalous and Spin Transport

Advanced Science, EarlyView.
Li‐ and V‐intercalated V2Se2O bilayers possess intralayer ferrimagnetic and interlayer ferromagnetic orders, alongside ferroelasticity, in‐plane uniaxial magnetic anisotropy, half‐metal/enhanced spin splitting, the anomalous Hall effect, giant magnetoresistance, tunneling magnetoresistance, near‐perfect spin filtering effect, spin Seebeck effect, and ...

Evolution of Mass Functions of Coeval Stars through Wind Mass Loss and Binary Interactions [PDF]

, 2015
Accurate determinations of stellar mass functions and ages of stellar populations are crucial to much of astrophysics. We analyse the evolution of stellar mass functions of coeval main sequence stars including all relevant aspects of single- and binary ...

Efficient Manipulation of Magnetic Domain Wall by Dual Spin‐Orbit Torque in Synthetic Antiferromagnets

Advanced Science, EarlyView.
Dual spin‐orbit torque coming from two Pt layers effectively drives the magnetic domain wall motion (DWM) in a synthetic antiferromagnet consisting of two Co ferromagnetic layers coupled with interlayer exchange coupling (IEC). In addition, the antisymmetric version of IEC leads to low current density for nucleating DW and fast velocity of DWM ...

Modeling blue stragglers in young clusters [PDF]

Research in Astronomy and Astrophysics, 2011
In this paper, a grid of the binary evolution models are calculated for the study of blue straggler (BS) population in intermediate age ($\log Age$=7.85-8.95) star clusters. The BS formation via mass transfer and merging is studied systematically using our models.

Magnetic and Crystal Symmetry Control on Spin Hall Conductivity in Altermagnets

Advanced Science, EarlyView.
Crystal structures and schematic illustrations of the spin Hall effect (SHE) in altermagnets. High‐symmetry RuO2 exhibits conventional SHE, while tilted RuO2 shows trivial unconventional SHE (USHE) caused by structural tilting. CrSb and MnTe, with reduced magnetic symmetry, display intrinsic USHE arising from symmetry‐driven spin–momentum locking ...

Electric Field Modulation of Interlayer Coupling via Piezostrain in a Synthetic Antiferromagnet

Advanced Science, EarlyView.
Controlling the interlayer exchange coupling (IEC) in synthetic antiferromagnets (SAFs) using an electric field is a promising route toward energy‐efficient spintronic devices. In this study, electric field induced‐strain modulation of IEC in Co/Ru/Co SAF/PMN‐PT is demonstrated.

Field Blue Stragglers and Related Mass Transfer Issues

, 2014
This chapter contains my impressions and perspectives about the current state of knowledge about field blue stragglers (FBS) stars, drawn from an extensive literature that I searched. I conclude my review of issues that attend FBS and mass transfer, by a

Contribution of primordial binary evolution to the two blue-straggler sequences in globular cluster M30

, 2017
Two blue-straggler sequences discovered in globular cluster M30 provide a strong constraint on the formation mechanisms of blue stragglers. We study the formation of the blue-straggler binaries through binary evolution, and find that binary evolution can
