A Precise Measurement of the Oxygen Isotope Effect on the Néel Temperature in Cuprates
Figure 5
(a) Oxygen isotope effect of (left) and (right) in YPrBaCuO taken from [5]. The O and O samples are in filled red circles and empty black squares, respectively. Figures (b) and (c) are demonstration of the IE using charge carriers density , instead of oxygen content . The values of are given in the figures. Green triangles () represent reduction of 2% in the number of charge carriers in the O samples compared to the O sample. In this case both and are functions of regardless of the isotope.
