Exchange interaction for the triplet superconductor UTe2 [PDF]

Scientific Reports, 2023
UTe2 is one triplet superconductor that defies conventional relation between ferromagnetism and superconductivity. Our search for a theoretical explanation starts with one spin-triplet state of two electrons and construct a two-particle exchange ...

Written feedback as interaction: Knowledge exchange or activity exchange? [PDF]

International Journal of the First Year in Higher Education, 2013
This paper examines in-text, handwritten feedback comments on first year undergraduate writing in the discipline of Statistics. Using a small corpus of annotated assignments, I examine the grammar choices and content choices made by tutors as they ...

Electron and hole spectrum taking into account deformation and polarization in the quantum dot heterostructure InAs/GaAs

Фізика і хімія твердого тіла, 2023
In the paper InAs spherical quantum dots in a GaAs matrix were investigated. The energies of electrons and holes in single- and multi-band models (with strong, weak, and intermediate spin-orbit interaction) were calculated taking into account both the ...

Pressure-dependent topological superconductivity on the surface of FeTe0.5Se0.5

New Journal of Physics, 2022
FeTe _1− _x Se _x is a family of iron-based superconductors with its critical temperature ( T _c ) dependent on the composition of Se. A well-known T _c is 14.5 K for x = 0.45, which exhibits an s -wave superconducting gap between the topological ...

Probing Magnetic Exchange Interactions with Helium [PDF]

Physical Review Letters, 2021
Controlling and sensing spin polarization of electrons forms the basis of spintronics. Here, we report a study of the effect of helium on the spin polarization of the tunneling current and magnetic contrast in spin-polarized scanning tunneling microscopy (SP STM).

Interplay of spin–orbit and exchange interaction in a ferromagnet/heavy-metal hybrid system: Ni on W(110)

New Journal of Physics, 2023
In a combined experimental and theoretical study, we investigate the interplay of spin–orbit interaction (SOI) and exchange interaction (XI) in the electronic structure of ultrathin Ni films on W(110). Using spin- and angle-resolved inverse photoemission,

Molecular S = 2 High-Spin, S = 0 Low-Spin and S = 0 ⇄ 2 Spin-Transition/-Crossover Nickel(II)-Bis(nitroxide) Coordination Compounds

Inorganics, 2021
Heterospin systems have a great advantage in frontier orbital engineering since they utilize a wide diversity of paramagnetic chromophores and almost infinite combinations and mutual geometries.

Topology and ground state control in open-shell donor-acceptor conjugated polymers

Cell Reports Physical Science, 2021
Summary: Donor-acceptor (DA) conjugated polymers (CPs) with narrow bandgaps and open-shell (diradical) character represent an emerging class of materials whose rich behavior emanates from their collective electronic properties and diminished electron ...

Effects of Spiro-Cyclohexane Substitution of Nitroxyl Biradicals on Dynamic Nuclear Polarization

Molecules, 2022
Spiro-substituted nitroxyl biradicals are widely used as reagents for dynamic nuclear polarization (DNP), which is especially important for biopolymer research. The main criterion for their applicability as polarizing agents is the value of the spin–spin

A Triplet/Singlet Ground-State Switch via the Steric Inhibition of Conjugation in 4,6-Bis(trifluoromethyl)-1,3-phenylene Bisnitroxide

Molecules, 2023
Ground triplet 4,6-bis(trifluoromethyl)-1,3-phenylene bis(tert-butyl nitroxide) (TF2PBN) reacted with [Y(hfac)3(H2O)2] (hfac = 1,1,1,5,5,5-hexafluoropentane-2,4-dionate), affording a doubly hydrogen-bonded adduct [Y(hfac)3(H2O)2(TF2PBN)].
