Exchange-biasing topological charges by antiferromagnetism

Nature Communications, 2018
Spin-polarized carriers could show an extra Hall component when moving through certain real-space topological spin textures. Here, He et al. report an exchange bias experienced by the topological spin textures living at the interface between a ...

Canted antiferromagnetism in phase-pure CuMnSb [PDF]

, 2018
We report the low-temperature properties of phase-pure single crystals of the half-Heusler compound CuMnSb grown by means of optical float-zoning. The magnetization, specific heat, electrical resistivity, and Hall effect of our single crystals exhibit an

Classical Antiferromagnetism in Kinetically Frustrated Electronic Models [PDF]

Physical Review Letters, 2014
We study the infinite U Hubbard model with one hole doped away half-filling, in triangular and square lattices with frustrated hoppings that invalidate Nagaoka's theorem, by means of the density matrix renormalization group.

Antiferromagnetism in metals: from the cuprate superconductors to the heavy fermion materials [PDF]

Journal of Physics: Condensed Matter, 2012
The critical theory of the onset of antiferromagnetism in metals, with concomitant Fermi surface reconstruction, has recently been shown to be strongly coupled in two spatial dimensions.

A model of d-wave superconductivity, antiferromagnetism, and charge order on the square lattice [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2023
Significance The cuprate compounds exhibit high-temperature superconductivity at ambient pressure and a complex phase diagram. Early studies proposed a connection between cuprate superconductivity and spin-liquid states characterized by excitations with ...

Robustness of antiferromagnetism in the Su-Schrieffer-Heeger Hubbard model [PDF]

Physical review B, 2021
We recently unveiled that antiferromagnetism (AFM) order can be dominantly induced by the bond Su-Schrieffer-Heeger (SSH) electron-phonon coupling (EPC), which is beyond the conventional wisdom that AFM order is usually driven by strong Coulomb ...

Spin mapping of intralayer antiferromagnetism and field-induced spin reorientation in monolayer CrTe2

Nature Communications, 2022
Intrinsic antiferromagnetism in van der Waals (vdW) monolayer (ML) crystals enriches our understanding of two-dimensional (2D) magnetic orders and presents several advantages over ferromagnetism in spintronic applications.

Strongly correlated antiferromagnetic vanadates

APL Materials, 2023
Antiferromagnetic (AFM) materials have zero net magnetic moments due to the alignment of adjacent magnetic moments antiparallel to each other, which have drawn extensive interest in the field of next generation spintronics, thanks to the merits of ...

Tunable high-temperature itinerant antiferromagnetism in a van der Waals magnet

Nature Communications, 2021
Discovery of two dimensional (2D) magnets, showing intrinsic ferromagnetic (FM) or antiferromagnetic (AFM) orders, has accelerated development of novel 2D spintronics, in which all the key components are made of van der Waals (vdW) materials and their ...

Voltage-Controlled Antiferromagnetism in Magnetic Tunnel Junctions. [PDF]

Physical Review Letters, 2020
We demonstrate a voltage-controlled exchange bias effect in CoFeB/MgO/CoFeB magnetic tunnel junctions that is related to the interfacial Fe(Co)O_{x} formed between the CoFeB electrodes and the MgO barrier.
