Magnetic model for A2CuP2O7 (A = Na, Li) revisited: 1D versus 2D behavior

S. Lebernegg, A. A. Tsirlin, O. Janson +4

We report magnetization measurements, full-potential band structure calculations, and microscopic modeling for the spin-1/2 Heisenberg magnets A2CuP2O7 (A = Na, Li). Based on a qua…

2H-NMR studies of supercooled and glassy aspirin

R. Nath, B. Geil, R. Bohmer

Acetyl salicylic acid, deuterated at the methyl group, was investigated using 2H-NMR in its supercooled and glassy states. Just above the glass transition temperature the molecular…

Coupled magnetic and ferroelectric states in the distorted honeycomb system Fe $_{4}$ Ta $_{2}$ O $_{9}$

Soumendra Nath Panja, Luminita Harnagea, Jitender Kumar +4

We report on the magnetic, thermodynamic, dielectric, and pyroelectric measurements on the hitherto unreported Fe $_{4}$ Ta $_{2}$ O $_{9}$ . This system is seen to exhibit a series of m…

NMR and Î¼SR study of spin correlations in SrZnVO(PO4)2 a S=1/2 frustrated magnet on a square lattice

L. Bossoni, P. Carretta, R. Nath +3

31P nuclear and muon spin-lattice relaxation rate measurements in SrZnVO(PO4)2, a S=1/2 frustrated magnet on a square lattice, are presented. The temperature (T) dependence of the…

Kelvon-roton instability of vortex lines in dipolar Bose-Einstein condensates

M. Klawunn, R. Nath, P. Pedri +1

The physics of vortex lines in dipolar condensates is studied. Due to the nonlocality of the dipolar interaction, the 3D character of the vortex plays a more important role in dipo…

Large magnetocaloric effect in the kagome ferromagnet Li $_{9}$ Cr $_{3}$ (P $_{2}$ O $_{7}$ ) $_{3}$ (PO $_{4}$ ) $_{2}$

Akshata Magar, Somesh K, Vikram Singh +7

Single-crystal growth, magnetic properties, and magnetocaloric effect of the $S = 3/2$ kagome ferromagnet Li $_{9}$ Cr $_{3}$ (P $_{2}$ O $_{7}$ ) $_{3}$ (PO $_{4}$ ) $_{2}$ (trigonal, space group: $P\bar{3}…
