Abstract

We perform an equivalence principle experiment for a magnetically shielded spin-polarized body of Dy ₆ Fe ₂₃. We use a single-pan mass comparator to compare the spin-polarized body with an unpolarized group of masses. The equivalence of spin-up and spin-down positions is good to (1.1 ±7.8)×10⁻⁹ in earth gravitational field.
