Journal ArticleDOI
Low-temperature spin freezing in the Dy 2 Ti 2 O 7 spin ice
J. Snyder,Benjamin G. Ueland,Joanna S.G. Slusky,Hemamala I. Karunadasa,R. J. Cava,Peter Schiffer +5 more
TL;DR: In this article, a study of the low temperature bulk magnetic properties of the spin ice compound with particular attention to the $(Tl4\mathrm{K})$ spin freezing transition was performed.
Journal ArticleDOI
Multiferroic behavior in the double-perovskite Lu 2 MnCoO 6
S. Yáñez-Vilar,Eundeok Mun,Vivien Zapf,Benjamin G. Ueland,J. S. Gardner,J. S. Gardner,J. D. Thompson,John Singleton,Manuel Sánchez-Andújar,Jorge Mira,N. Biskup,María Antonia Señarís-Rodríguez,Cristian D. Batista +12 more
TL;DR: In this article, a multiferroic member of the double perovskites was investigated using x-ray and neutron diffraction, specific heat, magnetization, electric polarization, and dielectric constant measurements.
Journal ArticleDOI
Strong cooperative coupling of pressure-induced magnetic order and nematicity in FeSe.
K. Kothapalli,Anna E. Böhmer,W. T. Jayasekara,Benjamin G. Ueland,Pinaki Das,Aashish Sapkota,Valentin Taufour,Yuming Xiao,E. Ercan Alp,Sergey L. Bud'ko,Paul C. Canfield,Andreas Kreyssig,Alan I. Goldman +12 more
TL;DR: In this article, it was shown that the magnetism and structural order in FeSe are strongly coupled and merge into a single first-order transition for pressures ≳ 1.7 GPa.
Journal ArticleDOI
Unconventional dynamics in triangular Heisenberg antiferromagnet NaCrO2.
A. Olariu,Philippe Mendels,Fabrice Bert,Benjamin G. Ueland,Peter Schiffer,Robert F. Berger,Robert J. Cava +6 more
TL;DR: While specific heat and magnetization measurements indicate the onset of a transition in the range Tc approximately 40-50 K, both muon spin rotation and NMR reveal a fluctuating crossover regime extending well below Tc, with a peak of relaxation rate T1(-1) around T approximately 25 K.
Journal ArticleDOI
Zero-point entropy in stuffed spin-ice
G. C. Lau,Rafael S. Freitas,Benjamin G. Ueland,B. D. Muegge,E. L. Duncan,Peter Schiffer,Robert J. Cava +6 more
TL;DR: In this article, the third law of thermodynamics dictates that the entropy of a system in thermal equilibrium goes to zero as its temperature approaches absolute zero, however, a residual entropy can be measured, attributable to a high degeneracy in the energetically preferred positions of hydrogen ions associated with the so-called ice rules.
