Abstract
An atom interferometer using a Bose-Einstein condensate of Rb atoms is utilized for the measurement of magnetic field gradients. Composite optical pulses are used to construct a spatially symmetric Mach-Zehnder geometry. Using a biased interferometer we demonstrate the ability to measure small residual forces in our system at the position of the atoms. These are a residual magnetic field gradient of 152 mG/cm and and an inertial acceleration of 0.080.02 m/s. Our method has important applications in the calibration of precision measurement devices and the reduction of systematic errors.
