| dc.description.abstract | The effect of compression on the magnetic ground state of Sr[subscript 2]IrO[subscript 4] is studied with x-ray resonant techniques in the diamond anvil cell. The weak interlayer exchange coupling between square-planar 2D IrO[subscript 2] layers is readily modified upon compression, with a crossover between magnetic structures around 7 GPa mimicking the effect of an applied magnetic field at ambient pressure. Higher pressures drive an order-disorder magnetic phase transition with no magnetic order detected above 17–20 GPa. The persistence of strong exchange interactions between J[subscript eff]=1/2 magnetic moments within the insulating IrO[subscript 2] layers up to at least 35 GPa points to a highly frustrated magnetic state in compressed Sr[subscript 2]IrO[subscript 4], opening the door for realization of novel quantum paramagnetic phases driven by extended 5d orbitals with entangled spin and orbital degrees of freedom. | en_US |
