Giant microwave absorption in fine powders of superconductors
G. Csősz, B. G. Márkus, A. Jánossy +8
Enhanced microwave absorption, larger than that in the normal state, is observed in fine grains of type-II superconductors (MgB and KC) for magnetic fields as small…
A time domain based method for the accurate measurement of Q-factor and resonance frequency of microwave resonators
B. Gyüre, B. G. Márkus, B. Bernáth +2
We present a novel method to determine the resonant frequency and quality factor of microwave resonators which is faster, more stable, and conceptually simpler than the yet existin…
Muon spin rotation study of the intercalated graphite superconductor CaC6 at low temperatures
F. Murányi, M. Bendele, R. Khasanov +4
Muon spin rotation (muSR) experiments were performed on the intercalated graphite CaC6 in the normal and superconducting state down to 20 mK. In addition, AC magnetization measurem…
High-field electron spin resonance spectroscopy study of GdOFFeAs superconductors
A. Alfonsov, F. Murányi, V. Kataev +16
We report a detailed investigation of GdOFFeAs (x = 0, 0.07 and 0.14) samples by means of high-field/high-frequency electron spin resonance (HF-ESR) together with mea…
Field Dependent Superfluid Density in the Optimally Doped SmFeAsO_(1-x)F_y Superconductor
S. Weyeneth, M. Bendele, R. Puzniak +9
The magnetic field dependence of the in-plane magnetic penetration depth for optimally doped SmFeAsO_(1-x)F_y was investigated by combining torque magnetometry, SQUID magnetometry,…
Generalized Elliott-Yafet theory of electron spin relaxation in metals: the origin of the anomalous electron spin life-time in MgB2
F. Simon, B. Dora, F. Muranyi +6
The temperature dependence of the electron spin relaxation time in MgB2 is anomalous as it does not follow the temperature dependence of the resistivity above 150 K, it has a maxim…
