Magnetic and Structural Properties of LaNiO<sub>3</sub> Single Crystals
ORAL
Abstract
RNiO3 (R = rare earth) perovskites form a series of compounds for which the magnetic and electronic properties have been studied for decades. All compounds possess an antiferromagnetic, insulating state, with the lone exception of LaNiO3 (LNO) which has traditionally been described as a Pauli paramagnetic metal. Previous bulk experimental investigations have been relegated to work on polycrystalline materials; however, recently, successful growth of single crystals of LNO was reported [1,2]. The single crystals obtained provide an opportunity for deeper investigations into the physics of LNO, and indeed the traditional view of LNO has been challenged by a report of an antiferromagnetic metallic ground state [2]. Here, we discuss the magnetic and structural properties of single crystal LNO prepared in our laboratory.
