The effect on effective area and voltage modulation depth of a serial superconducting quantum interference device (SQUID) magnetometer was simulated and observed. The variation in the effective area with the number N of serial SQUIDs was simulated. To reduce the beat phenomenon and optimize the serial SQUID magnetometer, the distance x between two adjacent SQUIDs should exceed 40 mu m or even 65 mu m, or dummy SQUIDs should be added at the edge of the serial SQUIDs. The optimal layout of a high-T(c) serial SQUID array is discussed. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2990069
