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…
Effect of magnesium doping on the orbital and magnetic order in LiNiO2
M. Bonda, M. Hopzapfel, Sophie De Brion +6
In LiNiO2, the Ni3+ ions, with S=1/2 and twofold orbital degeneracy, are arranged on a trian- gular lattice. Using muon spin relaxation (MuSR) and electron spin resonance (ESR), we…
Thickness dependent magnetic anisotropy of ultrathin LCMO epitaxial thin films
Norbert M. Nemes, Mar Garcia-Hernandez, Zsolt Szatmari +10
The magnetic properties of La0.7Ca0.3MnO3 (LCMO) manganite thin films were studied with magnetometry and ferromagnetic resonance as a function of film thickness. They maintain the…
Anisotropy of superconducting MgB2 as seen in electron spin resonance and magnetization data
F. Simon, A. Janossy, T. Feher +8
We have observed the conduction electron spin resonance (CESR) in fine powders of MgB2 both in the superconducting and normal states. The Pauli susceptibility is chi_s=2.0*10^{-5}…
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…
