Abstract
We have measured the ab-plane resistivity of LaSrCuO single crystals with small Sr content (x=0.052 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 curve starting at a temperature T 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 of superconducting samples just above .
