Effect of electron irradiation on rf-susceptibility of ferromagnetic superconductor EuFe<sub>2</sub>(As,P)<sub>2</sub>

ORAL

Abstract

High resolution AC magnetic susceptibility was measured in single crystals of ferromagnetic superconductor (TC=24K, TCurie=18K),
EuFe2(As,P)2 using tunnel diode resonator (TDR) in zero and in finite external DC magnetic fields. The same sample was irradiated with 2.5
MeV electrons at a dose that caused substantial changes of all features. Based on these and literature results, the intricate interplay between
superconductivity and ferromagnetism in this unique system will be discussed.
