“…Compared with the cuprate super-conductors, the most conspicuous feature of BKBO is the lack of two-dimensional CuO 2 planes. So the unconventional, most likely the magnetic origin driven mechanism proposed for cuprate superconductors may not be suitable for BKBO 19 . Some other anomalous features also have been discovered from the experiments, including a large oxygen isotope effect 20,21 and the softening of phonons in the BKBO system 22,23 .…”

“…This implies two possibilities: (a) λ tr ≪ λ and the pairing is due to EPI, or (b) λ tr ≃ λ but EPI is responsible for pairing by virtue of some peculiarities in the equations describing superconductivity -for instance because of non-Migdal vertex corrections. Related to this dilemma, it is worth mentioning that a similar puz- [28], while tunnelling measurements [29] give λ ∼ 1. Note, in Ba x K 1−x BiO 3 there are no magnetic fluctuations (or magnetic order) and no signs of strong electronic correlations.…”
