TL;DR: The results suggest that the low-temperature increase of [chi]([ital T]) is not a consequence of a single source of paramagnetic impurities in the samples but may arise from [ital S]=1/2 end-chain interactions.

TL;DR: Two nuclear-demagnetization cryostats, each containing 173 mol of copper coolant in a 8 T magnetic field and based on an Oxford Instruments model 1000 dilution refrigerator, have been under development at the University of Florida Microkelvin Laboratory for studies of nuclear magnetic ordering in metals and in solid3He, properties of superfluid3He at T≈0, and mesoscopic systems, and for development of primary thermometers based on population differences in nuclear quadrupole systems as mentioned in this paper.

TL;DR: High-density bcc and hcp3He have been cooled into the magnetically ordered state by direct nuclear demagnetization and the transition to the ferromagnetic state was observed.

TL;DR: The temperature dependent magnetic susceptibility of Ni(C2H8N2)2NO2(ClO4), known as NENP, has been measured from 400 K to 264 µK as discussed by the authors.

TL;DR: In this paper, the magnetic susceptibility of a polycrystalline, single-phase sample of CeAl{sub 3} has been measured from 10 K to below 800 K, and the temperature dependence of the susceptibility is consistent with the results of other groups and possesses a broad peak around 500 mK.
