Terahertz Magneto-optical investigation of quadrupolar spin-lattice effects in magnetically frustrated Tb2Ti2O7
K. Amelin, Y. Alexanian, U. Nagel +9
The significance of spin-lattice coupling in the phase diagram of the quantum spin-icepyrochlore Tb2Ti2O7 has been a topic of debate for some time. Here, we focus on the aspect of…
Unusual magnetoelectric effect in paramagnetic rare-earth langasite
L. Weymann, L. Bergen, Th. Kain +13
Violation of time reversal and spatial inversion symmetries has profound consequences for elementary particles and cosmology. Spontaneous breaking of these symmetries at phase tran…
Effects of Ca substitution on quasi-acoustic sliding modes in SrCaCuO
E. Constable, A. D. Squires, J. Horvat +8
The low energy lattice dynamics of the quasi-periodic spin-ladder cuprate SrCaCuO are investigated using terahertz frequency synchrotron radiation. A hig…
Archetypal soft-mode driven antipolar transition in francisite Cu3Bi(SeO3)2O2Cl
Cosme Milesi-Brault, Constance Toulouse, Evan Constable +8
Model materials are precious test cases for elementary theories and provide building blocks for the understanding of more complex cases. Here, we describe the lattice dynamics of t…
Field-induced double spin spiral in a frustrated chiral magnet
M. Ramakrishnan, E. Constable, A. Cano +14
We report the direct observation of a magnetic-feld induced long-wavelength spin spiral modulation in the chiral compound Ba3TaFe3Si2O14. This new spin texture emerges out of a chi…
Magnetic and dielectric order in the kagome-like francisite CuBi(SeO)OCl
E. Constable, S. Raymond, S. Petit +8
We report a single-crystal neutron diffraction and inelastic neutron scattering study on the spin 1/2 cuprate CuBi(SeO)OCl, complemented by dielectric and electric…
