Interctions between different magnetic materials at their interfaces or between magnetic materials and elements or compounds are extremely promising for future applications in Europe's industry. Such interfaces can either have strong spin-orbit interaction or can mediate directional (even chiral) interactions. They, therefore, play a key role for realizing useful new devices for computing, data storage and sensing. In parallel, crystal lattices lacking inversion symmetry have proven potential to show intrinsic torques.

Prominent examples are

- heavy metals (HMs) in contact with ferromagnets (FMs), where a strong torque on the FM can be created by sending a charge current through the HM,

- heterostructures that support chiral interactions, which lead to chiral magnetic ground states such as skyrmions promise new concepts for data storage and data processing,

- compounds or heterostructures with broken inversion symmetry that convert a charge current to a spin (or angular) moment,

- systems with giant Hall effects or spin Seebeck effects could lead to ultrasensitive magentometers.

This new field of research promises to produce new material systems that can enable both a stable and non-volatile storing of information in  nanoscale devices at room temperature or higher as well as an easy writing of the information with low power consumption. In addition a highly sensitive detection of magnetic fields at the nanoscale can enable new concepts for, e.g., life science in diagnostics.

To create progress, research on new materials, thin film systems and devices is urgently needed for the European community. Target properties such as stable chiral ground states at room temperature, large spin Hall angles, defined proximity induced moments in non-magnets or similar need materials and interfaces with engineered properties such as spin conductance, DMI-interaction, coherent electron transport adn similar.

Europe has reached a strong position in these fields in the last years. Support is necessary to keep and improve this situation by boosting groundbreaking basic science by Open Calls as well as by coordinating actions by networks for exchanging students, researchers and their ideas.
