New Upper Bounds on Exotic Neutron Spin-Electron Spin Interactions via Neutron Spin Rotation Measurements in a Compensated Ferrimagnet
T. Mulkey, K. N. Lopez, C. D. Hughes +16
We report a search for exotic spin-spin interactions between neutrons and electrons which could signal new physics beyond the Standard Model using slow neutron polarimetric imaging…

Polarized Neutron Measurements of the Internal Magnetization of a Ferrimagnet Across its Compensation Temperature
C. D. Hughes, K. N. Lopez, T. Mulkey +15
We present the first polarized neutron transmission image of a model Neel ferrimagnetic material, polycrystalline terbium iron garnet (Tb3Fe5O12, TbIG for short), as it is taken th…
