As the temperature decreased, the number of electron pairs increased and eventually saturated, leaving the remaining electrons in an antiferromagnetic arrangement. At very low temperatures ...

while the other half form weak pairs associated with charge ordering and lattice distortion. By comparing the valence electron arrangement identified in this study with previously reported spin ...

This enabled the study of valence electron arrangements within the crystal ... instead forming pairs. These pairs exhibited properties reminiscent of a superconducting state driven by charge ...
