Superconducting Tc and Electron-Phonon Coupling in Nb to 132 GPa: Magnetic Susceptibility at Megabar Pressures
We have measured superconducting Tc using a highly sensitive magnetic susceptibility technique to megabar pressures s.100 GPad. We observed anomalies in TcsPd for Nb at 5–6 GPa and 60–70 GPa, at which pressure Tc increases by 0.7 K and decreases by about 1 K, respectively. In contrast, Tc in Ta remains nearly constant up to 45 GPa. We suggest that the anomalies in Nb arise from stresssensitive ...
متن کاملMultiprobe experiments under high pressure: resistivity, magnetic susceptibility, heat capacity, and thermopower measurements around 5 GPa.
We have performed multiprobe experiments using a Bridgman-anvil pressure cell, adapted to trap Daphne oil as pressure medium. Resistivity, ac-magnetic susceptibility, thermopower, and ac-heat capacity of a type-I superconductor, lead, have been studied at low temperature up to 5+/-0.1 GPa. This is the first report where ac-magnetic susceptibility has been measured in this type of pressure cell ...
متن کاملStructure of liquid iron at pressures up to 58 GPa.
We report structural data on liquid iron at pressures up to 58 GPa measured by x-ray scattering in a laser heated diamond anvil cell. The determined structure factor preserves essentially the same shape along the melting curve. Our data demonstrate that liquid iron at high pressures is a close-packed hard-sphere liquid. The results place important constraints on the thermodynamic and transport ...
متن کاملMagnetic susceptibility measurements at high pressure using designer diamond anvils
High pressure magnetic susceptibility experiments can yield valuable insights into the changes in magnetic behavior and electron correlation properties which can accompany extreme compressions of matter. However, magnetic susceptibility experiments with ultrahigh pressure diamond anvil cells are extremely challenging due to the very small size of the high-pressure sample ~'75 mm diameter! and t...
متن کاملNonlinear magnetic susceptibility of ferrofluids
In ferrofluids, external magnetic fields can produce a nonlinearity in the dependence of magnetic susceptibilities on the field strength, due to both normal saturation and abnormal saturation. We derive the nonlinear magnetic susceptibility by using a Langevin model. Then, we investigate the nonlinear ac responses of the magnetic susceptibility by means of a perturbation expansion method and an...
