Oseroff et al. measured the EPR signal from Cu2+ ions, and
found a decrease of signal intensity below .
Brill et al. performed high-field ESR measurements and identified
singlet-triplet and triplet-triplet transitions .
Itoh et al. performed 63,65Cu-NMR and NQR measurements
, and found a drop of the 63Cu nuclear T1 relaxation rate
