Spin-phonon coupling in ZnCr2Se4
T. Rudolf, Ch. Kant, F. Mayr +3
Spin-phonon coupling and magnetodielectric effects of ZnCr2Se4 were investigated by means of infrared (IR) spectroscopy as a function of temperature and magnetic field. ZnCr2Se4 is…
Multiferroicity and colossal magneto-capacitance in Cr-thiospinels
J. Hemberger, P. Lunkenheimer, R. Fichtl +3
The sulfur based Cr-spinels RCr2S4 with R = Cd and Hg exhibit the coexistence of ferromagnetic and ferroelectric properties together with a pronounced magnetocapacitive coupling. W…
Colossal magnetostriction and negative thermal expansion in the frustrated antiferromagnet ZnCr2Se4
J. Hemberger, H. -A. Krug von Nidda, V. Tsurkan +1
A detailed investigation of ZnCr2Se4 is presented which is dominated by strong ferromagnetic exchange but orders antiferromagnetically at T_N = 21 K. Specific heat C and thermal ex…
Uniaxial pressure dependencies of the phase transitions in GdMnO
J. Baier, D. Meier, K. Berggold +4
GdMnO shows an incommensurate antiferromagnetic order below K, transforms into a canted A-type antiferromagnet below K, and for finite magnetic fields a…
Experimental evidence for competition of antiferromagnetic and ferromagnetic correlations in HgCr2S4
V. Tsurkan, J. Hemberger, A. Krimmel +5
A detailed study of poly- and single crystalline samples of the normal spinel HgCr2S4 is reported. The structural refinement reveals enhanced values of the atomic displacements sug…
The multiferroic phases of (Eu:Y)MnO3
J. Hemberger, F. Schrettle, A. Pimenov +5
We report on structural, magnetic, dielectric, and thermodynamic properties of (Eu:Y)MnO3 for Y doping levels 0 <= x < 1. This system resembles the multiferroic perovskite manganit…
Spin-driven Phonon Splitting in Bond-frustrated ZnCr2S4
J. Hemberger, T. Rudolf, H. -A. Krug von Nidda +4
Utilizing magnetic susceptibility, specific heat, thermal expansion and IR spectroscopy we provide experimental evidence that the two subsequent antiferromagnetic transitions in Zn…
Spin dynamics in the low-dimensional magnet TiOCl
D. V. Zakharov, J. Deisenhofer, H. -A. Krug von Nidda +9
We present detailed ESR investigations on single crystals of the low-dimensional quantum magnet TiOCl. The anisotropy of the g-factor indicates a stable orbital configuration below…
Colossal magnetocapacitance and colossal magnetoresistance in HgCr2S4
S. Weber, P. Lunkenheimer, R. Fichtl +3
We present a detailed study of the dielectric and charge transport properties of the antiferromagnetic cubic spinel HgCr2S4. Similar to the findings in ferromagnetic CdCr2S4, the d…

R. Nath, A. V. Mahajan, N. Buettgen +3
The magnetic properties of Na2CuP2O7 were investigated by means of 31P nuclear magnetic resonance (NMR), magnetic susceptibility, and heat capacity measurements. We report the 31P…
Hysteresis effects in the phase diagram of multiferroic GdMnO
J. Baier, D. Meier, K. Berggold +4
We present high-resolution thermal expansion and magnetostriction measurements of GdMnO, which develops an incommensurate antiferromagnetic order (ICAFM) below…
