Perovskite rare earth nickelates

Perovskite rare earth nickelates (RNiO3) have a rich phase diagram generated by changing the rare earth cation, R. The primary effect of this is to distort the structure, bending the nickel-oxygen-nickel bond angle. The exchange of one rare earth for another tunes the magnetic and electronic phases through a lattice distortion [1,2].

Much of the interest in nickelates is focused on predictions of high temperature superconductivity [3], their unusual antiferromagnetic order [4] and their sharp and highly controllable metal-insulator transition.

In Geneva we synthesise nickelate-based heterostructure as a base to study their intrinsic physics as well as to engineer novel properties arising from heterostructure effect such as unique magnetic structures, exchange bias and strain-, field- and light-tuning of the electronic state [5].

Bulk phase diagram of the perovskite nickelates RNiO3 showing how the metal-insulator transition and paramagnetic-antiferromagnetic transition can be tuned in temperature by rare earth cation size.
