Crossover from one-dimensional copper-oxygen chains to two-dimensional ladders charge transport in (La,Y)y(Sr,Ca)14-yCu24O41
T. Ivek, T. Vuletic, B. Korin-Hamzic +8
The charge transport in the copper-oxygen chain/ladder layers of (La,Y)y(Sr,Ca)14-yCu24O41 is investigated along two crystallographic directions in the temperature range from 50 K…
Mobility gap in intermediate valent TmSe
M. Dumm, B. Gorshunov, M. Dressel +1
The infrared optical conductivity of intermediate valence compound TmSe reveals clear signatures for hybridization of light - and heavy f-electronic states with m* ~ 1.6 m_0 and…

Suppression of Superconductivity in YBCO/LCMO Superlattices
F. Chen, B. Gorshunov, G. Cristiani +2
The competition of superconductivity and magnetism in superlattices composed of alternating YBaCuO and LaCaMnO thin films is investigated us…
Asymmetric Lineshape due to Inhomogeneous Broadening of the Crystal-Field Transitions in Mn12ac Single Crystals
S. Vongtragool, A. Mukhin, B. Gorshunov +1
The lineshape of crystal-field transitions in single crystals of Mn12ac molecular magnets is determined by the magnetic history. The absorption lines are symmetric and Gaussian for…
