Magnetic pair-breaking effects: Moment formation and critical doping level in superconducting systems (A=Fe,Co,Ni,Zn,Ga,Al)
We have conducted a systematic study on the effect of Cu-site doping in La 1.85 Sr 0.15
CuO 4 system. The relations between T c and doping level as well as the critical doping
levels xc have been determined accurately for the Fe-, Co-, Ni-, Zn-, Ga-, and Al-doped
systems. Every dopant either carries an intrinsic magnetic moment or induces a net moment
on the Cu-O 2 plane. The size of the moment is correlated with the suppression of
superconductivity, consistent with the magnetic-pair-breaking effect. The ground states of the …
