Na3[Ce(C7H3NO4)3] · 15H2O: A New Material for Millikelvin Thermometry

Abstract
Magnetic specific heat and susceptibility measurements have shown that Na3[Ce(C7H3NO4)3] · 15H2O has extremely weak effective spin-spin interactions, suggesting that this material may be a useful alternative to cerium magnesium sitrate for very low temperature thermometry.
