Competing interactions in quantum spin systems with geometric frustration can lead to disordered but highly correlated spin states. For decades, experimental research on antiferromagnetic (AFM) quantum kagome materials has been driven primarily by the hunt for the quantum spin liquid (QSL) ground state. [...]

POLI is a hot neutron two-axis diffractometer at the Heinz Maier-Leibnitz Zentrum (MLZ), Germany, which uses spin-polarized neutrons for magnetic studies in particular. The instrument is used, for instance, to study complex magnetic structures, to reconstruct magnetization densities in the unit cell, and to explore phase diagrams of materials via multiparameter studies. [...]

Scientific software in the geosciences often evolves organically, growing from small, purpose-built tools into long-lived infrastructure. Using the example of the TERENO observatories and their integration into the Earth Environment DataHub, this contribution reflects on the challenges and opportunities of transforming legacy systems into sustainable, community-ready platforms.​ A central task was the migration of sensor metadata from a tightly coupled legacy system to the Helmholtz Sensor Management System, requiring a clear separation of data and metadata, adaptation to new API-based technologies, and reconciliation of differing data models and vocabularies [...]
