  We conducted laboratory searching for the exotic spin- and velocity-dependent
new interactions according to the previously proposed experimental scheme. Two
$\sim$6Kg heavy source masses are rotationally modulated at a frequency of
20Hz. Four identical atomic magnetometers are used in an array form to increase
the statistics and cancel the common-mode noise. Data processing method based
on high precision numerical integration is applied for the four harmonic
frequencies of the signal. The rotation direction of the source masses was
reversed to flip the signal. Thus the [1,-3,3,-1] weighting method can be
applied to remove possible slow drifting further. The experiment method has
noise reduction features, and new constraints for Vector-Axial and Axial-Axial
were obtained. The new constraints on VA improved by as much as more than four
orders, on AA by as much as two orders in the corresponding force range,
respectively.
