Frustrated ground state in the metallic Ising antiferromagnet Nd2Ni2In

Journal Article · · Physical Review Materials
We use inelastic neutron scattering measurements to examine the inter-metallic Ising anti-ferromagnet \NNI. The dynamical structure factor displays a spectrum with multiple crystal field excitations. These crystal field excitations consist of a set of four transitions covering a range of energies between $$4$$ and $80$ meV. The analysis of the crystalline electric field scheme confirms the Ising nature of the spins and their orientation as proposed by previous studies. We characterize \NNI~as a large moment intermetallic antiferromagnet with the potential to support a geometrically frustrated Shastry-Sutherland lattice.
