High Pressure 3D to 2D Tuning of Magnetism in Cuprates

Broken lattice symmetries often play an integral part in the selection process of the electronic ground state. A prime example is found in the La-214 cuprates, where lattice distortions result in a complex relationship between superconductivity, charge and magnetic orders. In an attempt to dissect this problem into its various parts, here we highlight the impact of lattice distortions on the pristine magnetism of a cuprate parent compound.
