ab-plane resistivity and possible charge stripe ordering in strongly underdoped La$_{2-x}$Sr$_{x}$CuO$_{4}$ single crystals
Physica C 341-348, 1779 (2000) We have measured the ab-plane resistivity of La$_{2-x}$Sr$_x$CuO$_4$ single crystals with small Sr content (x=0.052 $\div$ 0.075) between 4.2 and 300 K by using the AC Van der Pauw technique. As recently suggested by Ichikawa et al., the deviation from the linearity of...

Summary: | Physica C 341-348, 1779 (2000) We have measured the ab-plane resistivity of La$_{2-x}$Sr$_x$CuO$_4$ single
crystals with small Sr content (x=0.052 $\div$ 0.075) between 4.2 and 300 K by
using the AC Van der Pauw technique. As recently suggested by Ichikawa et al.,
the deviation from the linearity of the $\rho_{\mathrm{ab}}(T)$ curve starting
at a temperature T$_{\mathrm{ch}}$ can be interpreted as due to a progressive
slowing down of the fluctuations of pre-formed charge stripes. An electronic
transition of the stripes to a more ordered phase could instead be responsible
for some very sharp anomalies present in the $\rho_{\mathrm{ab}}(T)$ of
superconducting samples just above $T_{\mathrm{c}}$. |
