Xl. Qian et al., OBSERVATION OF THE MAGNETIC OPTIC KERR-EFFECT OF THE Y-BA-CU-O SUPERCONDUCTING FILM IN A HIGH MAGNETIC-FIELD, Physica. C, Superconductivity, 235, 1994, pp. 1587-1588
The observation of the Kerr effect of the YBCO film at 77-100 K and th
e room temperature is reported. It is found that the effect is very we
ak even near the critical temperature. This result is consistent with
that of the magnetic circular dichroism measurement by other authors w
ith a He-Ne laser.
