New limit on Lorentz-invariance- and CPT-violating neutron spin interactions using a free-spin-precession He3-Xe129 comagnetometer.

TL;DR: An upper limit on the equatorial component of the background field interacting with the spin of the bound neutron b(⊥)(n)<8.4 × 10(-34) GeV is obtained.

TL;DR: An ultrasensitive low-field magnetometer based on the detection of free precession of colocated 3He and 129Xe nuclear spins is employed using SQUIDs as low-noise magnetic flux detectors to search for a spin-dependent P- and T-violating nucleon-nucleon interaction mediated by light pseudoscalar bosons.

TL;DR: In this paper, a low-field magnetometer based on the detection of free spin precession of gaseous, nuclear polarized 3He or 129Xe samples with a SQUID as magnetic flux detector is presented.

Systematic T1 improvement for hyperpolarized 129xenon.
TL;DR: The spin-lattice relaxation time T1 of hyperpolarized (HP)-(129)Xe was improved at typical storage conditions (i.e. low and homogeneous magnetic fields) and an "aging" process of the wall relaxation was identified by repeating measurements on the same cell.

TL;DR: In this paper, the authors measured magnetic field gradients from transverse relaxation rates of precessing spin samples using low-noise magnetic flux detectors, and determined the residual longitudinal field gradient across the spin sample to be (5.6 ± 0.2)pT/cm.
