Results of the high-frequency/field electron spin resonance investigation of the quantum S = 1/2 chain compound LiCu2O2 are presented. Spin-singlet ground state (which occurs in LiCu2O2 as a result of the spin-dimerization) is revealed at a temperature above T ~ 23 K. The size of the ...
2RuCu2O8 COMPOUND]]>doi:10.1142/S0217979203016315Topographic and spectroscopic information on GdSr2RuCu2O8 sintered pellets have been obtained by a home built low temperature Scanning Tunneling Microscope (STM) operating at 4.2 K. The topographic image of the surface showed non homogeneous samples ...
According to the obtained X-ray topography and diffractometry data, these crystals demonstrate misorientation anisotropy around different crystallographic axes, which is a consequence of incommensurate modulation in this compound. The highly perfect crystals grown by TSFZ method are found to demonstrate the...

A simple description has been proposed for the renormalization of the conduction band parameters in cuprates owing to the interaction of the current carriers with phonons. Kinks in the quasiparticle dispersion law in the optical phonon mode region (70 meV, compound Bi2Sr2CaCu2O8鈭 x ) and ...
