We describe a quantitative analysis of the low-temperature ({ital T}{lt}300 K) susceptibility ({chi}({ital T})) of La{sub 2{minus}x}Sr{sub x}CuO{sub 4+y} for dopant concentrations in the vicinity of the superconducting phase boundary (SPB) at {ital x}=0.055. This analysis is based on a phenomenological model for the temperature dependence consisting of a Curie-like 1/{ital T} term plus a term linear in {ital T}. We find that the former exhibits nontrivial doping dependence at the SPB, while the {ital T}-linear part accepts decomposition into a Pauli contribution and a portion which can be understood using spin-wave theory.
