Control of Quantum States in 4d/5d Transition Metal Oxides*
Invited
Abstract
A delicate balance between spin-orbit and other competing interactions inherent in 4d/5d materials offers a unique range of opportunities to uncover exotic states and physical properties that are intimately coupled to the crystal structure [1]. This unique feature provides us fertile ground to control quantum states by tuning the lattice of single crystals. Here we present and discuss two recent examples and their fundamental significance: (i) Pressure-induced transition from interlayer ferromagnetism to intralayer antiferromagnetism in Sr4Ru3O10 [2], and (ii) Electrical-current control of structural and physical properties in canted antiferromagnetic iridates [3].
