Formation of magnetic moments in the cuprate superconductor Hg0:8Cu0:2Ba2Ca2Cu3O8þd below Tc seen by NQR
We report pure zero field nuclear magnetic resonance (NQR) measurements on the optimally doped three layer highTc-compounds HgBaCaCuO and HgBaCaCuO(F) with Tc 1⁄4 134 K. Above Tc two Cu NQR line pairs are observed in the spectra corresponding to the two inequivalent Cu lattice sites. Below Tc the Cu NQR spectra show additional lines leading to the extreme broadened Cu NQR spectra at 4.2 K well ...
متن کاملOn the ”spin-freezing” mechanism in underdoped superconducting cuprates
The letter deals with the spin-freezing process observed by means of NMRNQR relaxation or by muon spin rotation in underdoped cuprate superconductors. This phenomenon, sometimes referred as coexistence of antiferromagnetic and superconducting order parameters, is generally thought to result from randomly distributed magnetic moments related to charge inhomogeneities (possibly stripes) which exh...

متن کاملMagnetic Field induced Dimensional Crossover Phenomena in Cuprate Superconductors and their Implications
We discuss the occurrence of crossing points in the magnetization temperature (m,T ) plane within the framework of critical phenomena. It is shown that in a two-dimensional superconducting slab of thickness ds mz (δ) versus temperature T curves measured in different fields H = H (0, sin (δ) , cos (δ)) will cross at the critical temperature Tc of the slab. In contrast, in a 3D anisotropic bulk s...
متن کاملنظریه میدان میانگین برای ابررسانایی مسی دمای بالا
Two decades ago the epoch making discovery of high Tc cuprate superconductivity by Bednorz and Müller shocked the world’s superconductivity community. However, already in 1979 and 1980, the first heavy fermion superconductor CeCu2Si2 and organic superconductor (TMTSF)2PF6 have been discovered respectively. Also we know now that all these superconductors are unconventional and nodal. Further t...
