Abstract
We present several kinds of Superconducting Quantum Interference Filters (SQIFs) which are all realized with high-Tc superconductors. All SQIFs use the same configuration of 30 loops of different size. The properties of these SQIF types - serial arrays, parallel arrays, and a combination of both - are discussed concerning their usefulness for magnetometry. These properties are the formation of the desired single voltage peak, its peak voltage and full width at half maximum, and the magnetic field noise. Concerning all parameters an improvement can be achieved with SQIFs of all types compared to a single SQUID.
