“…Now a question arises: can the strong electron-phonon interaction modify the antiferromagnetic exchange energy and thus the AF ordering temperature in the parent insulating compounds? Studies of the isotope effect on the AF ordering temperature could clarify this issue [64,65]. Fig.…”

We review various isotope effects in the high-Tc cuprate superconductors to assess the role of the electron-phonon interaction in the basic physics of these materials. Of particular interest are the unconventional isotope effects on the supercarrier mass, on the charge-stripe formation temperature, on the pseudogap formation temperature, on the EPR linewidth, on the spin-glass freezing temperature, and on the antiferromagnetic ordering temperature. The observed unconventional isotope effects strongly suggest that lattice vibrations play an important role in the microscopic pairing mechanism of high-temperature superconductivity.

“…Shortly thereafter, the oxygen isotope effect was investigated in underdoped Y123 [23] and in La 2− x Sr x CuO 4 [24]. In the case of high-temperature superconductors, we also showed that oxygen isotopic substitution also affects other properties, such as magnetic penetration depth [25], Néel temperature [26], paramagnetic resonance linewidth EPR [27] and, in a decisive way, the opening temperature of the so-called pseudo-gap [28]. Research on the oxygen isotope effect has been very fruitful and has been extended to other groups of materials, including giant magnetoresistive manganates [29], rare earth nickelates [30] and cobaltates [31].…”
