Broadband dielectric spectroscopy on single-crystalline and ceramic CaCu3Ti4O12
S. Krohns, P. Lunkenheimer, S. G. Ebbinghaus +1
We present dielectric measurements of the colossal dielectric constant material CaCu3Ti4O12 extending up to 1.3 GHz also covering so far only rarely investigated single crystalline…
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…
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…
