Journal ArticleDOI
Origin of apparent colossal dielectric constants
Peter Lunkenheimer,Vid Bobnar,Vid Bobnar,A. V. Pronin,A. V. Pronin,A. I. Ritus,A. A. Volkov,Alois Loidl +7 more
TL;DR: In this article, it was shown that the largest intrinsic dielectric constant observed so far in nonferroelectric materials is of order 10 − 2 − 2, which can be explained by depletion layers at the interface between sample and contacts or at grain boundaries.
Journal ArticleDOI
Nonintrinsic origin of the colossal dielectric constants in Ca Cu 3 Ti 4 O 12
TL;DR: In this paper, the dielectric properties of a material showing colossal values of the Dielectric constant were investigated over a broad temperature and frequency range extending up to $1.3 GHz.
Journal ArticleDOI
Néel-type skyrmion lattice with confined orientation in the polar magnetic semiconductor GaV4S8.

TL;DR: A new Néel-type of SkL describable as a superposition of spin cycloids in contrast to the Bloch-type SkL in chiral magnets described in terms of spin helices is found in the polar magnetic semiconductor GaV4S8 with rhombohedral (C3v) symmetry and easy axis anisotropy.
Journal ArticleDOI
Relaxor ferroelectricity and colossal magnetocapacitive coupling in ferromagnetic CdCr2S4.
Joachim Hemberger,Peter Lunkenheimer,R. Fichtl,H.-A. Krug von Nidda,Vladimir Tsurkan,Vladimir Tsurkan,Alois Loidl +6 more
TL;DR: Measurements on a simple cubic spinel compound with unusual, and potentially useful, magnetic and electric properties show ferromagnetic order coexisting with relaxor ferroelectricity, and the magnetocapacitive coupling reaches colossal values, approaching 500 per cent.
Journal ArticleDOI
Colossal dielectric constants in transition-metal oxides
TL;DR: In this paper, a detailed overview and discussion of the dielectric properties of CaCu3Ti4O12 and related transition-metal oxides with large dielectoric constants is provided.
