To meet the requirements of a high performance magnetometer used in a nanostatellite, attention has been focused on the design of horizontal tunneling magnetometer. To accurately evaluate the performance of the horizontal tunneling magnetometer, functional parameters of the work function need to be considered first. The theoretical formula of work function is derived, and work function experiments of a horizontal tunneling magnetometer introduced. The tunneling current results from the comb-driving voltage at tunneling electrodes. The tunneling effect occurs, which is identified by analyzing the relation between the tunneling current and the driving voltage. Values of the work function are calculated.
