The transition temperature of \(\mathrm{YBa}_{2} \mathrm{Cu}_{4} \mathrm{O}_{8}(124)\) is increased by about \(10 \mathrm{~K}\) by doping with calcium, whereas Ca substitution in \(\mathrm{Y}_{2} \mathrm{Ba}_{4} \mathrm{Cu}_{7} \mathrm{O}_{14+x}\) (247) has no effect on \(T_{\mathrm{c}}\).

The Cu substitution by Zn and Ni impurities and its influence on the mass renormalization effects in angle resolved photoelectron spectra (ARPES) of Bi 2 Sr 2 CaCu 2 O 8+d is addressed. We show that the nonmagnetic Zn atoms have much stronger effect both in nodal and antinodal parts of the Brillouin
