Generic role of the Dzyaloshinskii-Moriya interaction in nanocrystalline ferromagnets

Motivated by recent experimental results, this numerical micromagnetic study demonstrates that interfacial Dzyaloshinskii-Moriya interactions in nanocrystalline terbium induce spin misalignment between adjacent grains, causing the asymmetric scattering patterns observed in polarized neutron experiments and highlighting the DMI's generic impact on the macroscopic magnetic properties of defect-rich polycrystalline materials.

Switching Characteristics of Electrically Connected Stochastically Actuated Magnetic Tunnel Junction Nanopillars

This paper demonstrates that electrically coupling perpendicular magnetic tunnel junctions in parallel induces correlated stochastic switching through circuit-mediated voltage redistribution, a phenomenon that can be accurately modeled using Kirchhoff's laws and mapped onto an Ising Hamiltonian to reveal tunable effective spin-spin interactions.

Second Harmonic Generation Spectroscopy of the Surface Charge Density Wave in the Weyl Semimetal CoSi

Using temperature-dependent rotational anisotropy second harmonic generation, researchers identified a purely surface-driven charge density wave transition on CoSi (001) at 90 K that exhibits a critical exponent consistent with the 3D XY universality class, a result attributed to the coupling between surface Fermi-arc states and bulk topology.

Observation of magnetic quantum phase crossovers in a semiconductor spin ladder

This paper demonstrates the realization of a programmable Heisenberg spin ladder in a germanium quantum dot array, where tunable exchange interactions and Hamiltonian-learning protocols enable the quantitative mapping of magnetic quantum phase crossovers and the detection of higher-order spin correlations to establish the platform as a controllable system for studying quantum magnetism and unconventional superconductivity.
