Non-locally coupled, periodically arranged SQUIDs (Superconducting QUantum Interference
Devices) can form magnetic metamaterials exhibiting extraordinary properties, including tuneability
and dynamic multistability, which have been experimentally observed. It is demonstrated numerically
that they also exhibit complex dynamic states in which clusters of SQUIDs with synchronous dynamics
coexist with clusters that exhibit asynchronous behavior. These "chimera states" appear generically as a
result of the non-local, dipole-dipole magnetic coupling between SQUIDs, and they can be reached by
randomly initializing the system. They also affect measurable quantities and thus their presence can in
principle be detected with presently available experimental set-ups.
