Abstract We propose one-dimensional (1D) and two-dimensional (2D) arrays of magnetic surface microtraps for cold alkali atoms using some arrays of current-carrying wires and calculate the spatial distributions of magnetic fields from the 1D and 2D arrays of current-carrying wires. The field gradients and curvatures from a single magnetic microtrap are analysed, and some interesting and periodic magnetic-well microstructures are found. The result shows that the magnetic-field gradient greater than 2.4 x 105G/cm and the field curvature greater than 4.05 x 108G/cm2 can be generated in our array of magnetic microraps, which can be used to realize the 1D and 2D arrays of Bose-Einstein condensations (or 1D and 2D arrays of Bose clusters) by rf-induced evaporative cooling, and then to form 1D and 2D atomic magnetic lattices, even to prepare 1D and 2D photonic crystals.
