Vf. Masterov et al., A NEW ESR-SPECTRUM IN THE Y-CA-BA-LA-CU-O HIGH-T-C SUPERCONDUCTOR SYSTEM, Superconductor science and technology, 7(1), 1994, pp. 17-18
Electron spin resonance spectra (ESR) of YBa1.5La0.5CU3O7.21 and Y0.7C
a0.3Ba1.5La0.5Cu3O7.08 high-T-c superconductors (HTSC) were obtained u
sing 3 cm and 2 mm ESR spectrometers. A nearly isotropic Lorentz line
with a g factor of 2.0065 +/- 0.0005 was observed and interpreted as b
eing due to the electron located near a diamagnetic atom in the HTSC l
attice.
