Superconducting high entropy alloy (HEA) are emerging as a new class of superconducting materials. It provides a unique opportunity to understand the complex interplay of disorder and superconductivity. We report the synthesis and detail bulk and microscopic characterization of Nb60Re10Zr10Hf10Ti10 HEA alloy using transport, magnetization, specific heat, and muon spin rotation/relaxation (µSR) measurements. Bulk superconductivity with transition temperature TC = 5.7 K confirmed by magnetization, resistivity, and heat capacity measurements. Zero-field µSR measurement shows that the superconducting state preserves time-reversal symmetry, and transverse-field measurements of the superfluid density are well described by an isotropic s-wave model.

“…Finally, we consider a few example experimental spectra and compare them with mudirac computed results. The experimental spectra presented in this paper have utilised the ISIS pulsed neutron and muon source [ 43 ] and in particular were acquired on the RIKEN‐RAL beam‐lines [ 44,45 ] with the RIKEN Port 4 instrument. The experimental set‐up is shown in Figure 5.…”

We present a new open‐source software for the integration of the radial Dirac equation developed specifically with muonic atoms in mind. The software, called mudirac, is written in C++ and can be used to predict frequencies and probabilities of the transitions between levels of the muonic atom. In this way, it provides an invaluable tool in helping with the interpretation of muonic X‐ray spectra for elemental analysis. We introduce the details of the algorithms used by the software, show the interpretation of a few example spectra and discuss the more complex issues involved with predicting the intensities of the spectral lines. The software is available publicly at https://github.com/muon-spectroscopy-computational-project/mudirac.
