Emergence of ferromagnetic state due to structural disorder in pseudo-binary Ce(Fe0.9Co0.1)2 compound

This study demonstrates that introducing structural disorder through rapid quenching and severe plastic deformation in the pseudo-binary Ce(Fe0.9Co0.1)2 compound stabilizes a low-temperature ferromagnetic state by suppressing the first-order transition to the antiferromagnetic phase, a mechanism attributed to topological disorder rather than simple structural distortions, which consequently significantly reduces the material's magnetocaloric entropy change.

Towards a unified first-principles-based description of VO2_2 using DFT+DMFT with bond-centered orbitals

This study employs a unified DFT+DMFT approach using bond-centered orbitals to comprehensively describe the structural and electronic properties of VO2_2 across its full phase space, revealing that the M2 phase is a strain-dependent local energy minimum featuring coupled singlet and Mott insulating states, while the T phase acts as a transitional state between M1 and M2 behaviors.

Efficient Picosecond-Laser Lift-Off of Copper Oxide from Copper: Modelling and Experiment

This paper establishes a theoretical framework and validates it experimentally to demonstrate that the optimal fluence for maximizing the lifted-off area in picosecond laser lift-off of copper oxide is F0opt=e1FthF_0^{\mathrm{opt}} = e^{1} F_{\mathrm{th}}, which is substantially lower than the fluence required for maximum ablation volume.

Importance of Electronic Entropy for Machine Learning Interatomic Potentials

This paper demonstrates that conventional machine learning interatomic potentials fail to accurately model mixed-valence materials like NaFePO4 due to their inability to capture electronic entropy, but introducing explicit charge-state information into the potential's representation successfully resolves these errors and enables correct structural optimization and thermodynamic predictions.

Role of a Quarter-Wave Plate in Confocal Microscopy: Signature of Spin-Orbit Interactions

This paper demonstrates that embedding a single quarter-wave plate in a confocal microscope induces strong spin-orbit interactions that transform a Gaussian beam into a tunable Hermite-Gaussian-like mode while significantly enhancing the polarization extinction ratio, offering a simple method for spatial mode engineering in standard optical systems.

High Magnetoresistance Ratio on hBN Boron-Vacancy/Graphene Magnetic Tunnel Junction

This study utilizes density functional theory and non-equilibrium Green function methods to demonstrate that introducing monoatomic boron vacancies in hexagonal boron nitride layers sandwiching a three-atom-thick graphene layer creates a van der Waals magnetic tunnel junction capable of achieving a record-high tunneling magnetoresistance ratio of approximately 400% due to spin-dependent transmission differences between parallel and antiparallel magnetic configurations.

Optical Spin Sensing and Metamagnetic Phase Control in the 2D Van der Waals Magnet Yb3+-Doped CrPS4

This study demonstrates that Yb3+ doping in the 2D van der Waals antiferromagnet CrPS4 enables optical spin sensing and control by encoding collective magnetic ordering and metamagnetic spin-flop transitions into the sharp f-f luminescence of the dopants through strong magnetic superexchange coupling.
