Abstract: The demagnetization protocols for frustrated arrays of interacting single-domain permalloy nanomagnets are studied by rotating the arrays in a changing magnetic field. The results have shown that nonmonotonic variations in field magnitude around and below the coercive field are vital for demagnetization process.
