The proposed International Accelerator Facility at Gesellschaft fur Schwerionenforschung (GSI) has several new experimental devices that may require superconducting magnets to provide the required magnetic fields. Superferric magnets have been designed that allow the production of the required high gradients in the large aperture quadrupoles and also allow the insertion of sextupole and octupole inserts. Dipoles have been designed that fulfill the field uniformity and radiation resistance requirements. Most of the magnets are static field, but the New Experimental Storage Ring (NESR) needs magnets that ramp at 1 T/s. Solutions are presented that use warm iron to reduce losses.
