Ya. Genenko et al., INFLUENCE OF MAGNETIC-FIELD ON AC SUSCEPTIBILITY OF GDBA2CU3O6-CRYSTALS(DELTA SINGLE), Physica. B, Condensed matter, 211(1-4), 1995, pp. 257-259
The temperature dependence of the AC susceptibility of GdBa2Cu3O6.75 S
ingle crystals has been investigated for magnetic fields both along an
d normal to the c-axis. The temperature of the diamagnetism onset (T-o
n) decreases with increase of the magnetic field along the c-axis. In
magnetic fields perpendicular to the c-axis, T-on decreases at small m
agnetic fields and increases at high magnetic fields.
