Pressure-induced transitions in FePS: Structural, magnetic and electronic properties
Shiyu Deng, Siyu Chen, Bartomeu Monserrat +2
FePS is a prototype van der Waals layered antiferromagnet and a Mott insulator under ambient conditions, which has been recently reported to go through a pressure-induced dimen…
Comparative structural evolution under pressure of powder and single crystals of the layered antiferromagnet FePS
David M. Jarvis, Matthew J. Coak, Hayrullo Hamidov +9
The layered antiferromagnet FePS has been shown to undergo a structural transition under pressure linked to an insulator-metal transition, with two incompatible models previous…
Evolution of magnetic order in van-der-Waals antiferromagnet FePS through insulator-metal transition
Matthew J. Coak, David M Jarvis, Hayrullo Hamidov +14
Layered van-der-Waals 2D magnetic materials are of great interest in fundamental condensed-matter physics research, as well as for potential applications in spintronics and device…
Pressure dependence of ferroelectric quantum critical fluctuations
M. J. Coak, C. R. S. Haines, C. Liu +2
The effect of ferroelectric fluctuations on the temperature dependent dielectric constant of SrTiO(STO) has been long studied. Those fluctuations have been shown in recent ye…

Hyeong-Jin Kim, C. R. S. Haines, C. Liu +5
Cs2CuCl4 is known to possess a quantum spin liquid phase with antiferromagnetic interaction below 2.8 K. We report the observation of a new metastable magnetic phase of the triangu…
Hidden fluctuations close to a quantum bicritical point
Corentin Morice, Premala Chandra, Stephen E. Rowley +2
In this paper we describe physical properties arising in the vicinity of two coupled quantum phase transitions. We consider a phenomenological model based on two scalar order param…
Observation of a 4-spin Plaquette Singlet State in the Shastry-Sutherland compound SrCu2(BO3)2
Mohamed E. Zayed, Christian Rüegg, Julio Larrea +17
The study of interacting spin systems is of fundamental importance for modern condensed matter physics. On frustrated lattices, magnetic exchange interactions cannot be simultaneou…
Intrinsic Structural Disorder and the Magnetic Ground State in Bulk EuTiO3
A. P. Petrovic, Y. Kato, S. S. Sunku +8
The magnetic properties of single-crystal EuTiO3 are suggestive of nanoscale disorder below its cubic-tetragonal phase transition. We demonstrate that electric field cooling acts t…
On the role of intrinsic disorder in the structural phase transition of magnetoelectric EuTiO3
Mattia Allieta, Marco Scavini, Leszek Spalek +6
Up to now the crystallographic structure of the magnetoelectric perovskite EuTiO3 was considered to remain cubic down to low temperature. Here we present high resolution synchrotro…
