Critical slowing down near the multiferroic phase transition in MnWO
D. Niermann, C. P. Grams, P. Becker +3
By using broadband dielectric spectroscopy in the radiofrequency and microwave range we studied the magnetoelectric dynamics in the multiferroic chiral antiferromagnet MnWO. Ab…
Domain dynamics in the multiferroic phase of MnWO4
D. Niermann, C. P. Grams, M. Schalenbach +5
By using broadband linear and nonlinear dielectric spectroscopy we studied the magnetoelectric dynamics in the chiral antiferromagnet MnWO4. In the multiferroic phase the dielectri…
Dielectric properties of charge ordered LuFe2O4 revisited: The apparent influence of contacts
Daniel Niermann, Florian Waschkowski, Joost de Groot +2
We show results of broadband dielectric measurements on the charge ordered, proposed to be mul- tiferroic material LuFe2O4. The temperature and frequency dependence of the complex…
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…
Soft-mode behavior of electromagnons in multiferroic manganite
A. M. Shuvaev, J. Hemberger, D. Niermann +6
The behavior of the low-frequency electromagnon in multiferroic DyMnO3 has been investigated in external magnetic fields and in a magnetically ordered state. Significant softening…
