Low temperature thermodynamics of Yb6MoO12 and Lu6MoO12

Abstract

We report on thermodynamic properties of both rhombohedral and cubic phases of Yb6MoO12-δ supplemented by measurements of Lu6MoO12-δ() magnetic properties. Among these series, Yb6MoO12-δ() only exhibits signatures of magnetic long-range order at TN∼2.5 K which is confirmed by both physical property measurements and neutron powder diffraction. Low temperature specific heat measured down to 100 mK suggests the rearrangement of magnetic subsystem at T* = 500 mK. © 2018 Elsevier B.V.
