Phase stability of entropy stabilized oxides with the $α$ -PbO $_{2}$ structure

Solveig S. Aamlid, Graham H. J. Johnstone, Sam Mugiraneza +3

The prediction of new high entropy oxides (HEOs) remains a profound challenge due to their inherent chemical complexity. In this work, we combine experimental and computational met…

Direct confirmation of long-range magnetic order and evidence for multipoles in Ce $_{2}$ O $_{3}$

Alexandra Cote, J. Eddie Slimak, Astha Sethi +10

The sesquioxide, Ce $_{2}$ O $_{3}$ , has been a material of intense interest in recent years due to reports of an anomalous giant magnetodielectric effect and emergent mixed crystal f…

Experimental evidence for field induced emergent clock anisotropies in the XY pyrochlore Er $_{2}$ Ti $_{2}$ O $_{7}$

J. Gaudet, A. M. Hallas, J. Thibault +3

The XY pyrochlore antiferromagnet Er $_{2}$ Ti $_{2}$ O $_{7}$ exhibits a rare case of $Z_{6}$ discrete symmetry breaking in its $ψ_{2}$ magnetic ground state. Despite being well-studied theoreti…

Magnetic dilution and domain selection in the XY pyrochlore antiferromagnet Er $_{2}$ Ti $_{2}$ O $_{7}$

J. Gaudet, A. M. Hallas, D. D. Maharaj +7

Below $T_{N} = 1.1$ K, the XY pyrochlore Er $_{2}$ Ti $_{2}$ O $_{7}$ orders into a $k = 0$ non-collinear, antiferromagnetic structure referred to as the $ψ_{2}$ state. The magnetic order in Er $_{2}$ T…

Relief of Frustration in the Heisenberg Pyrochlore Antiferromagnet Gd $_{2}$ Pt $_{2}$ O $_{7}$

A. M. Hallas, A. Z. Sharma, Y. Cai +5

The gadolinium pyrochlores, Gd $_{2} B_{2}$ O $_{7}$ , are amongst the best realizations of antiferromagnetically coupled Heisenberg spins on a pyrochlore lattice. We present a magnetic chara…

Incipient Ferromagnetism in Tb2Ge2O7: Application of Chemical Pressure to the Enigmatic Spin Liquid, Tb2Ti2O7

A. M. Hallas, J. G. Cheng, A. M. Arevalo-Lopez +8

The origin of the spin liquid state in Tb $_{2}$ Ti $_{2}$ O $_{7}$ has challenged experimentalists and theorists alike for nearly 20 years. To improve our understanding of the exotic magneti…
