We performed zero and transverse field muon spin rotation experiments on a large number
of YB a 2 C u 3 O 6+ x samples. We detect the coexistence of antiferromagnetic (AF) short …

Zero-field electron spin resonance (ESR) of dilute Gd ions substituted for Y in the cuprate
superconductor YBa 2 Cu 3 O 6+ y is used as a novel technique for measuring the absolute …

High-resolution electron microscopy and electron diffraction are quite useful for structural
characterization of perovskite-type superconducting copper oxides on the atomic scale …

We investigate the effects the Copper and Oxigen atoms of the CuO-plane on magnetic
properties in the YBCO within the frame work of the Ising model by using the effective field …

We have performed extensive zero-field μ SR experiments on pure YBa 2 Cu 3 O 6+ y and
diluted Y-rare-earth substituted Y 0.92 Eu 0.08 Ba 2 Cu 3 O 6+ y and Y 0.925 Nd 0.075 Ba 2 …

High-purity and homogeneous YBa2Cu3Oy single crystals with carrier doping level near the
AFM-SC boundary have been obtained in the oxygen content range between y= 6.340 and …

We have studied the electronic structure of unoccupied states measured by O K-edge and
Cu L-edge x-ray absorption spectroscopy (XAS), combined with crystal structure studied by …

We have examined the effects of 20-keV electron irradiation on the [-Cu (1)-O (1)-] n chain-
oxygen arrangements in oxygen-deficient but otherwise twin-free Y Ba 2 Cu 3 O 7− δ single …

Supraleitung Seit mehr als 50 Jahren das maßgebliche deutschsprachige Lehrbuch zur
Supraleitung Supraleitung, also das Verschwinden des elektrischen Widerstands in …

We present the results on heavily underdoped Y 1− x Ca x Ba 2 Cu 3 O 6+ y, which provide
the evidence that the doping mechanism (cation substitution or oxygen loading) directly …
