Magnetic properties of high-pressure optical floating-zone grown LaNiO3 single crystals

Sought-after single crystals of LaNiO3 were grown recently at the Kirchhoff Institute for Physics, Heidelberg University by means of the optical floating-zone method at oxygen pressures of 40 and 80 bar using a ScIDre HKZ furnace. The magnetic analysis of the samples indicates that long-range magnetic order is not intrinsic and most likely arising due to oxygen deficient phases.
