A layered erbium phosphonate in pseudo-D5h symmetry exhibiting field-tunable magnetic relaxation and optical correlation†
Abstract
A layered erbium(III) phosphonate compound, [Er(notpH4)(H2O)]ClO4ยท3H2O (1), in which the ErIII ion has a pseudo-D5h symmetry exhibits field tunable multiple magnetic relaxation. The near-IR emission spectrum of 1, excited at 1064 nm (Nd:YAG laser), provides a direct probe of the crystal field splitting correlated to the magnetic data.
