Novel spin excitation spectrum of trilayer nickelate Pr4Ni3O10 single crystals
Abstract: The captivating realm of rare earth nickelates, with their complex and diverse oxidation states of nickel, has been a persistent source of scientific inquiry. This enduring interest is driven by the fascinating interplay of phenomena such as metal-insulator transitions, metal-to-metal transitions accompanied by spin density waves (SDWs) and charge density waves (CDWs), and the emergence of novel superconductivity. Among these rare-earth nickelate superconductors, PrNiO stands out due to its fascinating magnetic properties, which exhibit bootstrapped dimensional crossover magnetism. Despite significant interest, the origin of this bootstrapped dimensional crossover magnetism in PrNiO remains unclear, including the exact nature of the interaction between the Pr and Ni ions, as well as the role of Fermi surface nesting and local moment interactions in driving these magnetic behaviors. Furthermore, how these magnetic properties couple with pressure-induced superconductivity in the material is still an open question. By analyzing the spin excitation dispersions, we aim to determine the effective magnetic exchange interaction parameters and achieve a deeper understanding of the relationship between magnetism and pressureinduced superconductivity in nickelates.
