High Frequency EPR Spectroscopy of Germanium Cuprate. I. The Case of Doping with Cobalt
S. V. Demishev, A. V. Semeno, N. E. Sluchanko +7
Resonant magnetoabsorption spectra for CuGeO3 single crystals containing 2% of Co impurity are studied in the frequency range 60-360 GHz in magnetic field up to 16 T at temperature…
ab-plane tunneling and Andreev spectroscopy of superconducting gap and pseudogap in (Bi,Pb)2Sr2Ca2Cu3O10 and Bi2Sr2CaCu2O8
A. I. D'yachenko, V. Yu. Tarenkov, R. Szymczak +4
We have measured the temperature dependence of gap features revealed by Andreev reflection Delta_s and by tunneling Delta in the ab-plane of optimal and slightly overdoped microcry…
Decay of spin-Peierls state in CuGeO3:Fe. The case of a strong disorder
S. V. Demishev, R. V. Bunting, A. A. Pronin +7
Influence of doping by iron impurity on spin-Peierls state in CuGeO3 is studied. ESR measurements for the frequency/temperature domain 60-450 GHz/ 1.8-300 K and specific heat data…
Experimental evidence for a spin gap in the s=1/2 quantum antiferromagnet Cu(OH)CO
E. Janod, L. Leonyuk, V. Maltsev
Magnetic properties of the natural mineral Cu(OH)CO (malachite) were investigated through DC and AC susceptibility measurements. The analysis of the low-temperature par…
Critical Currents, Pinning Forces and Irreversibility Fields in (YxTml-x)Ba2Cu3O7 Single Crystals with Columnar Defects in Fields up to 50 T
L. Trappeniers, J. Vanacken, L. Weckhuysen +8
We have studied the influence of columnar defects, created by heavy-ion (Kr) irradiation with doses up to 6 10^11 Kr-ions/cm2, on the superconducting critical parameters of single…
Magnetic Resonance of the Intrinsic Defects of the Spin-Peierls Magnet CuGeO3
A. I. Smirnov, V. N. Glazkov, L. I. Leonyuk +2
ESR of the pure monocrystals of CuGeO3 is studied in the frequency range 9-75 GHz and in the temperature interval 1.2-25 K. The splitting of the ESR line into several spectral comp…
