  • Conventional studies of nanomagnets often overlook the role of intermediate states in energy relaxation pathways. Here, the authors explore a simple nanomagnet model, revealing how geometry affects these pathways through multipolar analysis, with implications for understanding magnetic frustration and metastability in artificial spin ice, supported by magnetic force microscopy experiments.

  • Aerosol impacts have not been comprehensively considered in the cost-benefit integrated assessment models that are widely used to analyze climate policy. Here the authors account for these impacts and find that the health co-benefits from improved air quality outweigh the co-harms from increased near-term warming, and that optimal climate policy results in immediate net benefits globally.

  • Theoretical understanding of the interaction between electron vortex beams (EVBs) and magnetic samples is important for practical application in 3D magnetic imaging. The authors calculated the EVB magnetic phase shift upon transmission and developed a corresponding phase-reconstruction method, enabling potential robust implementations of EVB-based phase microscopy in magnetic as well as chiral materials.
