Probing interleaved magnetic and bond frustration and their interplay in a layered triangular lattice system

Abstract: The LnCd3P3 (Ln = La, Ce, Pr, Nd) family of materials is gaining attention as a platform for studying magnetic frustration, bond frustration, and their interplay. The Ln-ions are arranged on ideal 2D triangular lattice with layers that are well-separated from one another, promoting geometric magnetic frustration, while the CdP3 planes which are interleaved between the Ln layers exhibit a bond instability below 200 K and distort from three equal-length bonds to a long-range-frustrated two-long/one-short bond pattern with fluctuations persisting to near 300 K. The magnetic species of the family exhibit a range of anomalous properties suggesting a strong interplay between the layers. We propose a comparative local probe study of NdCd3P3 and its non-magnetic counterpart LaCd3P3 in the range T = 1.5 < T < 200 K in order to explore the possibility of internal time-reversal symmetry breaking, the temperature evolution of the anomalously small low temperature Nd3+ magnetic moment, and the relationship between the local magnetic response and bond frustration.
