Here we present inelastic neutron scattering measurements from the frustrated, quantum spin-1/2 chain material linarite, PbCuSO_4(OH)_2. Time of flight data, taken at 0.5K and zero applied magnetic field reveals low-energy dispersive spin wave excita

Low-temperature neutron diffraction and NMR studies of field-induced phases in linarite are presented for magnetic fields H∥b axis. A two-step spin-flop transition is observed, as well as a transition transforming a helical magnetic ground state in

We present an extensive microscopic magnetic study of the quasi-one-dimensional frustrated $s=\frac{1}{2}$ spin-chain compound linarite. Angular-dependent susceptibility and $^{1}\mathrm{H}$-NMR measurements were performed at various temperatures in

The structure of Cd3Cu4, solved by S. Samson in 1966, crystallizes with 1124 atoms in a cubic face-centred unit cell with a = 25.871 A . 568 atoms in the unit cell have icosahedral coordination. Close to this composition quasicrystalline icosahedral
