Altermagnetic Band Splitting in 10 nm Epitaxial CrSb Thin Films
Advanced Materials, EarlyView.Thin film altermagnets are attractive for potential spintronic applications. How thin can we make an altermagnet before quantum confinement perturbs the distinctive band structure? This paper uses angle‐resolved photoemission spectroscopy to show that the canonical g‐wave altermagnet, NiAs‐type CrSb, grown by molecular beam epitaxy, preserves its ...

Magnetic and pair correlations of the Hubbard model with next-nearest-neighbor hopping
, 1995 A combination of analytical approaches and quantum Monte Carlo simulations is used to study both magnetic and pairing correlations for a version of the Hubbard model that includes second-neighbor hopping $t^{\prime }=-0.35t$ as a model for high ...

Tunable Magnetism and Intrinsic Exchange Bias in Al‐Substituted Terbium Iron Garnet
Advanced Materials, EarlyView.Al substitution in terbium iron garnet thin films enables continuous tuning of the magnetic compensation temperature from 190 K to above room temperature. Near compensation, a giant intrinsic exchange bias emerges, whose sign and stochasticity can be controlled by external fields and cooling history. This approach provides new routes to engineer garnet

Reconfigurable Magnetotransport in MnBi2Te4 via Gate and Magnetic Field Tuning
Advanced Materials, EarlyView.Gate‐tunable magnetoresistance sign reversal under in‐plane magnetic fields is observed in an ultrathin MnBi2Te4 device, arising from spin reorientation and distinct scattering mechanisms. Moreover, angular‐dependent measurements reveal clear gate‐controlled magnetotransport anisotropy, underscoring the strong coupling between gating, spin ...

Antiferromagnetism and Superconductivity in layered organic conductors: Variational cluster approach
, 2006 The $\kappa$-(ET)$_2$X layered conductors (where ET stands for BEDT-TTF) are studied within the dimer model as a function of the diagonal hopping $t^\prime$ and Hubbard repulsion $U$.
