We describe the use of magnetic optical elements for manipulating beams of laser-cooled neutral atoms for atom optics and atom interferometry. Results are presented for the reflection of free-falling, laser-cooled caesium atoms from periodic structures consisting of an array of permanent rare-earth magnets of alternating polarity, ferromagnetic grid structures with micron-scale periodicities, and an array of parallel wires alternately carrying current in opposite directions.
