AA-stacked bilayer graphene in an applied electric field: Tunable antiferromagnetism and coexisting exciton order parameter [PDF]
, 2014 We study the electronic properties of AA-stacked bilayer graphene in a transverse electric field. The strong on-site Coulomb repulsion stabilizes the antiferromagnetic order in such a system.

Diluted Graphene Antiferromagnet [PDF]
Physical Review Letters, 2007 We study RKKY interactions between local magnetic moments for both doped and undoped graphene. We find in both cases that the interactions are primarily ferromagnetic for moments on the same sublattice, and antiferromagnetic for moments on opposite sublattices.

Advanced Functional Materials, EarlyView.EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Ferro and antiferromagnetism of ultrafine‐grained hematite
Geochemistry, Geophysics, Geosystems, 2014 Aluminum‐substituted hematite (here referred to as Al‐Hm) is an important magnetic mineral for paleo and environmental magnetism. However, the magnetic properties of nanosized Al‐Hm are poorly known.

Superconductivity and antiferromagnetism in a hard-core boson spin-1 model in two dimensions
, 2002 A model of hard-core bosons and spin-1 sites with single-ion anisotropy is proposed to approximately describe hole pairs moving in a background of singlets and triplets with the aim of exploring the relationship between superconductivity and ...

Mechanism of basal-plane antiferromagnetism in the spin-orbit driven iridate Ba2IrO4 [PDF]
, 2014 By ab initio many-body quantum chemistry calculations, we determine the strength of the symmetric anisotropy in the 5d5 j 1/2 layered material Ba2IrO4.

Itinerant antiferromagnetism in FeGe2 [PDF]
Physica B: Condensed Matter, 1997 FeGe_2, and lightly doped compounds based on it, have a Fermi surface driven instability which drive them into an incommensurate spin density wave state. Studies of the temperature and magnetic field dependence of the resistivity have been used to determine the magnetic phase diagram of the pure material which displays an incommensurate phase at high ...

Switching of Magnetic Order via Non‐Magnetic Al Addition in FeCoNiMnAlx Films
Advanced Functional Materials, EarlyView.Non‐magnetic Al addition provides a sensitive handle to switch the magnetic order in high entropy FeCoNiMnAlx thin films via fcc to bcc phase transformation. Films with fcc structure exhibit a large exchange bias, while bcc films exhibit enhanced ferromagnetic properties, reflecting the magnetic ground state of Mn which switches from antiferromagnetic ...

Itinerancy and Hidden Order in $URu_2Si_2$
, 2005 We argue that key characteristics of the enigmatic transition at $T_0= 17.5K $ in $URu_2Si_2$ indicate that the hidden order is a density wave formed within a band of composite quasiparticles, whose detailed structure is determined by local physics.

Holographic model for the paramagnetism/antiferromagnetism phase transition [PDF]
, 2014 In this paper we build a holographic model of paramagnetism/antiferromagnetism phase transition, which is realized by introducing two real antisymmetric tensor fields coupling to the background gauge field strength and interacting with each other in a ...
