Magnetoelastic Coupling in the Spin-Dimer SystemTlCuCl3

Cu nuclear spin - spin coupling in the dimer singlet state in SrCu 2 ( BO

We report results of nuclear magnetic resonance (NMR) experiments in SrCu 2 (BO 3) 2 , a quasi two-dimensional spin system with a singlet ground state. When magnetic field is applied along the c-axis, each of the quadrupole split Cu resonance lines splits further into four lines. The spin-echo intensity for some of the split lines oscillates against the separation time between π/2 and π rf-puls...

Nuclear spin-spin coupling in a van der Waals-bonded system: xenon dimer.

Nuclear spin-spin coupling over van der Waals bond has recently been observed via the frequency shift of solute protons in a solution containing optically hyperpolarized (129)Xe nuclei. We carry out a first-principles computational study of the prototypic van der Waals-bonded xenon dimer, where the spin-spin coupling between two magnetically non-equivalent isotopes, J((129)Xe - (131)Xe), is obs...

Giant magnetoelastic coupling in a metallic helical metamagnet.

Using high resolution neutron diffraction and capacitance dilatometry we show that the thermal evolution of the helimagnetic state in CoMnSi is accompanied by a change in interatomic distances of up to 2%, the largest ever found in a metallic magnet. Our results and the picture of competing exchange and strongly anisotropic thermal expansion that we use to understand them sheds light on a new m...
