Evolution of the local superconducting density of states in ErRh${}_4$B${}_4$ close to the ferromagnetic transition

V. Crespo, J. G. Rodrigo, H. Suderow +3

We present local tunneling spectroscopy experiments in the superconducting and ferromagnetic phases of the reentrant superconductor ErRh${}_4$B${}_4$. The tunneling conductance curve…
