Complex spin density wave ordering in La4Ni3O10
Abstract
The discovery of high-temperature superconductivity in layered nickelates under pressure has recently triggered enormous interest. Studies of these compounds have revealed a density-wave-like transition at ambient pressure, though its connection with superconductivity is still not well understood. Here, we report a detailed µSR study on single crystals of trilayer nickelate La4Ni3O10 at ambient pressure. We have identified a spin-density-wave (SDW) transition at the temperature of 𝑇N∼130K, as well as a broad crossover around 70–100 K. Based on the temperature dependence of the muon precession amplitudes and magnetic susceptibility, we attribute this additional crossover either to a spin reorientation, or to an inhomogeneous SDW ordering.
