Spin-spin correlations of the spin-ladder compound (CHN)CuBr measured by magnetostriction and comparison to Quantum Monte Carlo results
Fabrizio Anfuso, Markus Garst, Achim Rosch +4
Magnetostriction and thermal expansion of the spin-ladder compound piperidinium copper bromide (CHN)CuBr are analyzed in detail. We find perfect agreement betwee…
Diverging thermal expansion of the spin-ladder system (CHN)CuBr
T. Lorenz, O. Heyer, M. Garst +4
We present high-resolution measurements of the -axis thermal expansion and magnetostriction of piperidinium copper bromide \hp. The experimental data at low temperatures i…
Thermal expansion of the magnetically ordering intermetallics RTMg (R = Eu, Gd and T = Ag, Au)
J. Rohrkamp, O. Heyer, T. Fickenscher +5
We report measurements of the thermal expansion for two Eu- and two Gd-based intermetallics which exhibit ferro- or antiferromagnetic phase transitions. These materia…
Thermodynamics of the coupled spin-dimer system TlCuCl3 close to a quantum phase transition
T. Lorenz, S. Stark, O. Heyer +4
We present thermal expansion alpha, magnetostriction and specific heat C measurements of \tal, which shows a quantum phase transition from a spin-gap phase to a Neel-ordered ground…
A New Multiferroic Material: MnWO4
O. Heyer, N. Hollmann, I. Klassen +6
We report the multiferroic behaviour of MnWO, a magnetic oxide with monoclinic crystal structure and spiral long-range magnetic order. Based upon recent theoretical predictions…
