摘要：

Zero-field susceptibility and specific heat of Pb[CU(SO4)(OH)(2)] (linarite) single crystal were measured. In order to verify that linarite is a quasi-one-dimensional system with competing nearest-neighbour and next-nearest-neighbour in-chain exchange interaction (J(1) approximate to -30 K, J(2) approximate to 15 K), theoretical results based on electronic structure calculations within the LDA and a phenomenological modelling using the finite-temperature transfer-matrix method are taken into account. The possibility of various ground states is discussed in terms of the screened onsite repulsion Us: commensurate Neel or spin-Peierls phases versus incommensurate spiral states with acute or obtuse pitch angles.
