Antiferromagnetic Heisenberg S=5/2 spin chain compound SrMnVO
Sandra K. Niesen, Oliver Heyer, Thomas Lorenz +1
Large single crystals of the new compound SrMnVO have been grown by the floating-zone method. This transition-metal based oxide is isostructural to SrNiVO,…
Measurements of thermodynamic and transport properties of EuC: a low-temperature analogue of EuO
O. Heyer, P. Link, D. Wandner +2
EuC is a ferromagnet with a Curie-temperature of K. It is semiconducting with the particularity that the resistivity drops by about 5 orders of magnitude on co…
Magnetostrictive Neel ordering of the spin-5/2 ladder compound BaMn2O3: distortion-induced lifting of geometrical frustration
M. Valldor, O. Heyer, A. C. Komarek +3
The crystal structure and the magnetism of BaMnO have been studied by thermodynamic and by diffraction techniques using large single crystals and powders. BaMnO is…
Resistivity and Hall effect of LiFeAs: Evidence for electron-electron scattering
O. Heyer, T. Lorenz, V. B. Zabolotnyy +7
LiFeAs is unique among the broad family of FeAs-based superconductors, because it is superconducting with a rather large K under ambient conditions although it is a…
Superconductivity in SnO: a Nonmagnetic Analog to Fe-based Superconductors?
M. K. Forthaus, K. Sengupta, O. Heyer +6
We found that under pressure SnO with alpha-PbO structure, the same structure as in many Fe-based superconductors, e.g. beta-FeSe, undergoes a transition to a superconducting state…
Phase diagram and isotope effect in (PrEu)_0.7Ca_0.3CoO_3 cobaltites exhibiting spin-state transitions
A. V. Kalinov, O. Yu. Gorbenko, A. N. Taldenkov +11
We present the study of magnetization, thermal expansion, specific heat, resistivity, and a.c. susceptibility of (PrEu)CaCoO cobaltites. The measure…
