Abstract

The magnetic properties of EuAlSi, a compound comprising a honeycomb lattice of Al and Si atoms and a triangular lattice of Eu atoms, are presented. Moreover, we have prepared the Eu1-xSrxAlSi solid solution, to study the evolution of the collective quantum properties from the ferromagnetic EuAlSi towards the superconducting SrAlSi. A possible quantum critical point is suggested to exist in the vicinity of to x of 0.96, at which the suppression of ferromagnetic order is concomitant with the emergence of superconductivity.
