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…
Electronic and ionic conductivities in superionic LiC
D. Quintavalle, B. G. Márkus, A. Jánossy +7
The GHz microwave conductivity, and high field, GHz electron spin resonance (HF-ESR) of LiC fulleride is measured in a wide temperature range. We sugge…
Spin-stretching modes in anisotropic magnets: spin-wave excitations in the multiferroic Ba2CoGe2O7
K. Penc, J. Romhányi, T. Rõõm +10
We studied spin excitations of the multiferroic Ba2CoGe2O7 in high magnetic fields up to 33 T. In the electron spin resonance and far infrared absorption spectra we found several s…
Origin of the ESR spectrum in the Prussian Blue analogue RbMn[Fe(CN)6]*H2O
Á. Antal, A. Jánossy, L. Forró +3
We present an ESR study at excitation frequencies of 9.4 GHz and 222.4 GHz of powders and single crystals of a Prussian Blue analogue (PBA), RbMn[Fe(CN)6]*H2O in which Fe and Mn un…
Magnetic Field Induced Low-Energy Spin Excitations in YBa2Cu4O8 Measured by High Field Gd3+ ESR
Titusz Feher, Andras Janossy, Gabor Oszlanyi +5
We have measured the spin susceptibility of the underdoped high temperature superconductor, YBa2Cu4O8 by Gd^{3+} electron spin resonance in single crystals and aligned powders at s…
Comment on ``Magnetoresistance Anomalies in Antiferromagnetic YBaCuO: Fingerprints of Charged Stripes''
Andras Janossy, Ferenc Simon, Titusz Feher
In a recent Letter Ando et al (cond-mat/9905071) discovered an anomalous magnetoresistance(MR) in hole doped antiferromagnetic YBaCuO, which they attributed to char…
