Abstract
The magnetic Ln$^{3+}$ ions in the fergusonite and scheelite crystal
structures form a distorted or stretched diamond lattice which is predicted to
host exotic magnetic ground states. In this study, polycrystalline samples of
the fergusonite orthotantalates $M$-LnTaO$_4$ (Ln = Nd, Sm, Eu, Gd, Tb, Dy, Ho,
Er) are synthesized and then characterized using powder diffraction and bulk
magnetometry and heat capacity. TbTaO$_4$ orders antiferromagnetically at 2.25
K into a commensurate magnetic cell with $\vec{k}=0$, magnetic space group
14.77 ($P2_1$$'/c$) and Tb moments parallel to the $a$-axis. No magnetic order
was observed in the other materials studied, leaving open the possibility of
exotic magnetic states at $T<2$ K.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
