Priority Programme "Manipulation of Matter Controlled by Electric and Magnetic Fields: Towards Novel Synthesis and Processing Routes of Inorganic Materials" (SPP 1959)
Deutsche Forschungsgemeinschaft (DFG)
The Senate of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) established the Priority Programme Manipulation of Matter Controlled by Electric and Magnetic Fields: Towards Novel Synthesis and Processing Routes of Inorganic Materials (SPP 1959). The programme is designed to run for six years. The present call invites proposals for the second three-year funding period.

The objective of the Priority Programme is to develop a unified description of matter transport activated in inorganic solid materials by electric and magnetic fields based on experimental evidence, theoretical modelling, and computational simulation. Irreversible transformations from an initial state (which can be a mixture of solid state reactants, powder compacts, or already fully dense polycrystalline materials) into a final state (new phase, modified microstructure, deformation state) will be considered. In that respect, defects such as single or clustered point defects, dislocation networks, interfaces between two reacting solids, grain boundaries, or pores play a key role, as their structure and mobility determine the response of the whole material.

The research will be focused on the following areas:
- synthesis and phase formation by solid-state reactions and diffusive phase transformations
- densification of particle-based materials and microstructure coarsening (pore elimination and grain growth)
- mechanical deformation (plasticity and creep)

The focus on coupled effects under applied electromagnetic, chemical, and mechanical fields will be intensified.
A further essential goal of this Priority Programme is to link atomistic mechanisms to macroscopic behaviour in a multi-scale approach. The challenge is to combine advanced simulation methods at different time and length scales to predict microstructure evolution and properties such as the deformation behaviour, which can be experimentally assessed. This goal can only be reached by bringing groups from these disciplines together to combine their complementary expertise. Therefore, reference to other proposals within the programme is required and joint proposals are encouraged.

Model materials with defined composition and properties are preferred, in order to systematically investigate the effects of a particular type of electromagnetic loading.

The materials under focus are metals and intermetallics, oxide and non-oxide ceramics in their solid state, so that different types of interatomic bonds and electric/magnetic properties can be covered. The selected materials may be investigated as bulk, thin or thick films. Major constitutive phases should be crystalline. Polymers and polymer-based composites are excluded.

The external fields considered are pure, homogeneous electric or magnetic fields, with constant or time-dependent amplitude. Frequencies from the microwave regime and above will be excluded. Only synthesis and processing methods of solid phases relying on the irreversible effects of electromagnetic loading will be considered.
