Abstract

We performed muon spin rotation/relaxation/resonance (mu SR) experiments to investigate the dimensionality of the magnetic lattice of copper hydroxylhalide that is a prototype for layer-structured organic and inorganic hybrids. mu SR measurement under zero magnetic field revealed that an implantedmuon stops around the oxygen atoms in the CuO layer rather than the halideanions, permitting us to use the muon as a probe for local magnetic field at the oxygen site. Two local fields of 5.8 and 66 mT were observed for Cu-2(OH)I-3 in its ordered phase by decoupling experiment under longitudinal field, while three fields (3.9, 32 and 84 mT) were deduced for Cu-2(OH)(3)Cl. This result indicates that the two sails differ in magnetic structure. Weobserved a two-headed mu SR resonance line and a single-peak line for the paramagnetic phase of the Cl and I salts, respectively. We concluded that the doublet in the Cl spectrum is due to a ferromagnetic interaction proposed by our solid-state high-resolution deuterium NMR experiment. (C) 2001 Elsevier Science Ltd.
