Search for anomalous spin-dependent forces with a polarized-mass torsion pendulum
Abstract
The existence of hypothetical anomalous spin-dependent forces is investigated using spin-polarized Dy6Fe23 masses acting on ones of unpolarized copper in a dynamic-mode torsion pendulum. An upper limit is provided for the strength of an anomalous interaction of the dipole-monopole form at ranges from 1 to 100 cm.
