Quantum criticality in the spin- Heisenberg chain system copper pyrazine dinitrate

Oliver Breunig, Markus Garst, Andreas Klümper +3

The magnetic insulator copper pyrazine dinitrate comprises antiferromagnetic spin-1/2 chains that are well described by the exactly solvable one-dimensional Heisenberg model, provi…

CdV2O4: A rare example of a collinear multiferroic spinel

G. Giovannetti, A. Stroppa, S. Picozzi +11

By studying the dielectric properties of the geometrically frustrated spinel CdV2O4, we observe ferroelectricity developing at the transition into the collinear antiferromagnetic g…

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…

Thermal expansion of the spin-1/2 Heisenberg-chain compound Cu(CHN)(NO)

J. Rohrkamp, M. D. Phillips, M. M. Turnbull +1

Compounds containing magnetic subsystems representing simple model spin systems with weak magnetic coupling constants are ideal candidates to test theoretical predictions for the g…

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…
