High field magnetization anisotropy in cubic CeIn<sub>3</sub> single crystal

ORAL

Abstract

Cubic CeIn3 is a heavy fermion material that displays fascinating phenomena including pressure and field-induced quantum criticality, antiferromagnetism, Fermi surface transformations, and unconventional superconductivity. By using a large magnetic field with strength comparable to the crystal field energy scale, CeIn3 shows a non-trivial phase diagram depending on the field orientation from resistivity measurement [1]. To begin to understand the complex interplay of these phenomena, we have derived a minimal low energy Kondo lattice model containing material specific first-principles and spectroscopic input. To validate this model, we have derived the magnetic exchange interaction of the full J = 5/2 multiplet, and computed the anisotropic magnetization versus magnetic field. In this talk, I will discuss magnetization measurements of CeIn3 along the three principle directions [100], [110], and [111] up to 60 T to derive the cubic anisotropy of the exchange interactions. The results reasonably validate our theoretical low energy model that includes the excited crystal field levels.
