Multiferroicity in an organic charge-transfer salt that is suggestive of electric-dipole-driven magnetism
Peter Lunkenheimer,Jens Müller,Stephan Krohns,F. Schrettle,Alois Loidl,Benedikt Hartmann,Robert Rommel,Mariano de Souza,Mariano de Souza,Chisa Hotta,John A. Schlueter,Michael Lang +11 more
TL;DR: Evidence is provided for ferroelectricity, accompanied by antiferromagnetic spin order, in a two-dimensional organic charge-transfer salt, thus representing a new class of multiferroics, and a charge-order-driven mechanism leading to electronic ferroElectricity is proposed.

Multiferroicity in an organic charge-transfer salt: Electric-dipole-driven magnetism
Peter Lunkenheimer,Jens Müller,Stephan Krohns,F. Schrettle,Alois Loidl,Benedikt Hartmann,Robert Rommel,M. de Souza,Chisa Hotta,John A. Schlueter,Michael Lang +10 more
TL;DR: In this article, a new class of multiferroics, called purely electronic ferroelectricity, where charge order breaks inversion symmetry, has attracted considerable interest, which can be found in frustrated antiferromagnets with helical spin order.

Assessment of strain-induced cavitation of silica-filled styrene-butadiene rubber nanocomposite by synchrotron radiation tomography
C.E. Federico,Yves Fleming,Ondřej Kotecký,Robert Rommel,Adrian-Marie Philippe,Stephan Westermann,Frédéric Addiego +6 more
TL;DR: In this article , the authors employed Synchrotron radiation micro-computed tomography (SR μCT) to study the cavitation phenomena upon cyclic tensile loading prior to and after thermal exposure of silica-filled styrene-butadiene rubber nanocomposites cured at different temperatures.

Nonlinear electronic transport in the anomalous metallic state of quasi‐2D organic superconductors κ‐(BEDT‐TTF)2X
TL;DR: In this paper, the first and thirdharmonic voltage response in ac electronic transport measurements, representing the linear (ohmic) and nonlinear resistivity, respectively, of the quasi-two-dimensional (2D) organic superconductors κ-(BEDT-TTF)2X.

Partially ordered vortex lattices in the high-field low-temperature mixed state of quasi-two-dimensional organic superconductors
A. Maniv,V. Zhuravlev,Tsofar Maniv,Oren Ofer,Robert Rommel,Jens Müller,Jeff Sonier,Jeff Sonier +7 more
TL;DR: In this paper, the authors reported the results of high-field, low-temperature measurements of the quasi-two-dimensional organic superconductors and showed that the lineshapes for these compounds indicate the existence of partially ordered vortex lattice phases in the high-magnetic field regime.
