This article describes the project to build a pulsed magnetic field user laboratory at the Forschungszentrum Rossendorf near Dresden. Using a 50 MJ/24 kV capacitor bank, pulsed fields and rise times of 100 T/10 ms, 70 T/100 ms, and 60 T/1 s should be

The dynamics of adsorbed hydrogen molecules on the pore surface of Vycor glass has been investigated with a torsional oscillator technique at temperatures between 7.5 K and 22 K. Whereas most experiments carried out previously on this system were per

We have measured ac susceptibility, nuclear magnetic resonance, and nuclear heat capacity of two PtFexsamples with concentrations of magnetic impurities x = 11 ppm and 41 ppm at magnetic fields (0 ± 0.05) mT≤B≤248 mT. The susceptibility data hav

The ratio of nuclear saturation magnetization and superconducting critical field, μ0Msat/ BS0*≡∈, classifies the strength of mutual influence of nuclear magnetism and superconductivity. In order to investigate the interplay of both phenomena for

We report our recent investigations of the phase separation of liquid 3 He– 4 He mixtures in the restricted geometry of porous Vycor glass using pressure measurements. The experimental cell is entirely filled with a Vycor cylinder and closed by a c

We have measured the temperature dependence of the superconducting critical field of Al in the temperature range 17μK ≤ T ≤ 600mK. The external magnetic field necessary to suppress superconductivity in Al decreases significantly with decreasing

The crystal structure of the lowest-temperature -phase of has been determined as a function of temperature by neutron powder diffraction. The diffraction measurements show that there are no additional phases at low temperatures. Magnetic measurements

We have demagnetized a 2.92 mole Al sample of 6 N purity and measured its nuclear specific heat at temperatures 21 μK≤T≤20 mK and in magnetic fields of 11.4 mT≤B≤69.0 mT. In addition, we have performed nuclear magnetic resonance experiments

Nuclear magnetic resonance, ac susceptibility, and nuclear heat capacity of Pt samples with different concentrations of magnetic impurities x in the ppm range have been studied at magnetic fields (0 ± 0.05) mT ≤ B≤248 mT and at temperatures 0.3
