Carrier doping and interlayer coupling in HTSC single crystals
Abstract
Experimental results of the effect of carrier doping on the irreversibility lines in (La, Sr) 2CuO 4-δ and Bi 2Sr 2CaCu 2O 8+δ single crystals are summarized. As a function of Sr or oxygen contents, systematic and dramatic widening of the irreversible regions in the B - T phase diagram was observed in both systems. The present study suggests the critical importance of carrier concentration which directly affects the interlayer coupling strength and dimensionality of the flux line lattice in all the layered HTSC compounds as a universal feature.
