Abstract

We present a method of designing test masses with a high density of electron spins for use in mechanical experiments searching for weak spin interactions. Nested arrangements of rare-earth permanent magnets are shown to achieve spin densities of order 10(24) spins kg(-1) together with stray magnetic fields at negligible levels. A full magnetostatic analysis of the proposed designs is presented, the mechanical feasibility is analyzed and the related manufacturing issues are addressed.
