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…
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…
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…
Multiferroic behavior in CdCr2X4 (X = S, Se)
J. Hemberger, P. Lunkenheimer, R. Fichtl +3
The recently discovered multiferroic material CdCr2S4 shows a coexistence of ferromagnetism and relaxor ferroelectricity together with a colossal magnetocapacitive effect. The comp…
