Dielectric signatures of crystal-field and low-temperature correlated dynamics in NdMgAl11O19

Sonu Kumar, Gaël Bastien, Maxim Savinov +3

We report dielectric spectroscopy of single-crystalline \ce{NdMgAl11O19}, a magnetoplumbite hexaaluminate in which localized \ce{Nd^{3+}} moments coexist with a polarizable \ce{AlO…
