An ¹⁶⁶Er-Mossbauer Investigation of ErNiAl₄

Abstract:

A low temperature ¹⁶⁶Er-Mössbauer spectroscopy investigation of ErNiAl₄ reveals that the Er³⁺ ion’s ground state Kramers doublet has ¦Jz¦ just 8% less than the fully-stretched value of J = 15/2. The persistence of a magnetically-split spectrum to well above T_N = 5.8 K is consistent with Orbach type paramagnetic relaxation that proceeds via the third excited crystal field level.
