Nuclear magnetism in the second layer of 3He films on graphite has been studied as a function of density in the zero-field limit at temperatures down to 300 µK. Total surface coverages in this study ranged from 20 atoms/nm2 (the lowest coverage at w

We report measurements of the magnetic susceptibility of liquid 3He at saturated vapor pressure in the normal state from the superfluid transition temperature up to 1 K. Our results are comparable to those of Ramm, et al.1 at temperatures above 200 m

3 He films on graphite provide a model system for 2D magnetism. At low temperatures, the thermodynamic properties of these films are dominated by exchange interactions. However more subtle interactions such as dipolar coupling and other anisotropies

We have measured the absolute thermodynamic magnetization of 3 He in all of its liquid phases while using a new calibration technique which relies on the nuclear paramagnetism over the entire temperature range below 1 K as measured by Ramm, et al. We

The difference between total thermodynamic magnetizations in the $A$ and $B$ phases of superfluid ${}^{3}\mathrm{He}$ was measured at the equilibrium $A$- $B$ transition temperature over the entire range of applicable magnetic fields at pressures fro

We have measured the thermodynamic magnetization in the various phases of normal and superfluid3He. The A-B discontinuity differs from that inferred from nuclear-specific (NMR) experiments. We offer reasons why this apparent disagreement can be consi

We present data for the magnitude of the thermodynamic magnetization discontinuity at the equilibrium A-B transition in superfluid3He, ΔMAB, over its entire pressure-temperature-magnetic field phase diagram. The data was taken by measuring flux chan

We have developed an integrated dc SQUID magnetometer with additional positive feedback (APF) for low frequency true NMR applications. The APF scheme allows direct coupled read out from the SQUID to room temperature electronics and eliminates the nee

Conventional s-wave superconductors have order parameters with no internal degrees of freedom - they are characterized by an amplitude and a phase. All unconventional superconductors share the property of a nontrivial internal symmetry which makes th
