Pb(OF)Cu3(SeO3)2(NO3): a selenite fluoride nitrate with a breathing kagomé lattice†
Abstract
The Cu2+-based breathing kagomé material Pb(OF)Cu3(SeO3)2(NO3) with both corner-sharing and edge-sharing has been synthesized. Magnetic measurements suggest ferromagnetic interactions inside the layers and antiferromagnetic interactions between the neighboring layers, leading to an antiferromagnetic ground state with a field-induced spin–flip transition at low temperature.
