The effect of stress and strain on the electromagnetic properties of superconducting composite conductors is one of the key issues for the practical application of superconductivity. To discuss these subjects thoroughly, the International Workshop on Mechanical–Electromagnetic Properties of Composite Superconductors (MEM) has been held regularly since 2001. The 6th workshop (MEM11) was held in Okinawa, Japan in 2011, which was the centennial of the discovery of superconductivity by Professor Kamerlingh Onnes, as well as the 25th anniversary of the discovery of high temperature superconductors (HTS). Although it was originally planned that MEM11 be held in Mito, the workshop venue was changed because of the serious disaster in the north of Japan on 11 March 2011. Sixty five scientists participated in this specialized workshop. Fifty six papers were presented in the following six sessions: (1) Intrinsic strain effects on low temperature superconductors (LTS) and HTS, (2) The International Thermonuclear Experimental Reactor (ITER), (3) Strain evaluation by quantum beams, (4) Flux pinning properties of HTS, (5) Standardization and the Versailles Project on Advanced Materials and Standards (VAMAS) and (6) High field magnets. Several large topics were presented and discussed at the workshop: the important progress in methods for non-invasive measurements of the local strain exerted on the superconducting components in superconducting wires and cables using quantum beam techniques. This approach provides powerful tools for investigating the effect of strain in composite superconductors; the intrinsic strain effects in LTS and HTS in the reversible strain region. Recently, it has become easier to determine quantitatively the strain dependence of critical current when the local strain is measured directly, and the mechanical and electromagnetic properties of the superconductors used in the ITER tokamak. This was a major topic at the workshop since the superconducting magnets are a critical component in this project. Standardization with respect to ITER was also discussed, as well as other topics related to improving the mechanical–electromagnetic properties of practical HTS, including (RE)BCO, BSCCO and MgB2 wires. From such exciting and excellent presentations, nineteen papers were selected and invited for publication in this special issue. At the end of the workshop, a senior member of the International community thanked our Japanese colleagues for their exceptional hospitality and for holding this important workshop at this difficult time.
