A cascade of magnetic phase transitions and a 1/3-magnetization plateau in selenite–selenate Co₃(SeO₃)(SeO₄)(OH)₂ with kagomé-like Co²⁺ ion layer arrangements: the importance of identifying a correct spin lattice

Abstract

We prepared a new compound, Co3(SeO3)(SeO4)(OH)2, possessing layers of kagomé-like arrangement of Co2+ (spin S = 3/2) ions. This phase crystallizes in an orthorhombic space group Pnma (62) with unit...
