We propose a simple scaling procedure for the normal-state magnetization Mn data collected as functions of temperature T in different magnetic fields H. As a result, the Mn(T) curves collected in different fields collapse on to a single Msc(T) line. In this representation, the onset of superconducting diamagnetism manifests itself by a sharp divergence of the Msc(T) curves for different H values. As will be demonstrated, this allows for a reliable determination of temperature Tonset, at which superconducting diamagnetism become observable.
The recently discovered superconductor, UTe$_2$, has attracted immense scientific interest due to the experimental observations that suggest odd-parity superconductivity. It is believed that the material becomes a heavy-fermion metal at low temperatu
We report on muon spin rotation (muSR) studies of the superconducting and magnetic properties of the ternary intermetallic stannide Ca3Ir4Sn13. This material has recently been the focus of intense research activity due to a proposed interplay of ferr
We discuss the analysis of mixed-state magnetization data of type-II superconductors using a recently developed scaling procedure. It is based on the fact that, if the Ginzburg-Landau parameter kappa does not depend on temperature, the magnetic susce
We compute the two-particle quantities relevant for superconducting correlations in the two-dimensional Hubbard model within the dynamical cluster approximation. In the normal state we identify the parameter regime in density, interaction, and second
We report measurements of the specific heat, Hall effect, upper critical field and resistivity on bulk, B-doped diamond prepared by reacting amorphous B and graphite under high-pressure/high-temperature conditions. These experiments establish unambig
