Structural characterization and magnetic properties of chromium jarosite KCr3(OD)(6)(SO4)(2)
Potassium chromium jarosite, KCr3(OH)(6)(SO4)(2) (Cr-jarosite), is considered a promising candidate to display spin liquid behavior due to the strong magnetic frustration imposed by the crystal structure. However, the ground state magnetic properties have ...
ROYAL SOC CHEMISTRY2020Scale-invariant magnetic anisotropy in RuCl(3)at high magnetic fields
Philip Johannes Walter Moll, Maja Deborah Bachmann
Scale-invariant magnetic anisotropy in RuCl(3)has been revealed through measurements of its magnetotropic coefficient, providing evidence for a high degree of exchange frustration that favours the formation of a spin liquid state. In RuCl3, inelastic neutr ...

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Nicola Casati, Helmuth Berger, Lin Yang, Gregory Scott Tucker, Virgile Yves Favre, Romain Sibille
We report magnetic properties of a 3d(9) (Cu2+) magnetic insulator Cu2OSO4 measured on both powder and single crystal. The magnetic atoms of this compound form layers whose geometry can be described either as a system of chains coupled through dimers or as ...
AMER PHYSICAL SOC2020Magnetic dynamics across the in-field transition in Ca3Co2O6
Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Nagabhushan Ganesh Hegde
The discovery of multiple coexisting magnetic phases in the crystallographically homogeneous compound Ca3Co2O6 has stimulated ongoing research activity. In recent years the main focus has been on the zero-field-state properties, where exceedingly long time ...
AMER PHYSICAL SOC2020Two coupled chains are simpler than one: field-induced chirality in a frustrated spin ladder
Although the frustrated (zigzag) spin chain is the Drosophila of frustrated magnetism, our understanding of a pair of coupled zigzag chains (frustrated spin ladder) in a magnetic field is still lacking. We address this problem through nuclear magnetic reso ...
2020Magnetic-field-induced reorientation in the spin-density-wave and the spin-stripe phases of the frustrated spin-1/2 chain compound beta-TeVO4
beta-TeVO4 is a frustrated spin-1/2 zig-zag chain system, where spin-density-wave (SDW), vector-chiral (VC) and an exotic dynamic spin-stripe phase compete at low temperatures. Here we use torque magnetometry to study the anisotropy of these phases in magn ...
2020Structural and Dynamical Properties of Potassium Dodecahydro-monocarba-closo-dodecaborate: KCB11H12
Mirjana Dimitrievska, Wei Zhou
MCB11H12 (M: Li, Na) dodecahydro-monocarba-closo-dodecaborate salt compounds are known to have stellar superionic Li+ and Na+ conductivities in their high-temperature disordered phases, making them potentially appealing electrolytes in all-solid-state batt ...
AMER CHEMICAL SOC2020Multiphase magnetism in Yb2Ti2O7
We use neutron scattering to show that ferromagnetism and antiferromagnetism coexist in the low T state of the pyrochlore quantum magnet Yb2Ti2O7. While magnetic Bragg peaks evidence long-range static ferromagnetic order, inelastic scattering shows that sh ...
NATL ACAD SCIENCES2020Multiple Magnetic Bilayers and Unconventional Criticality without Frustration in BaCuSi2O6
Frédéric Mila, Bruce Normand, Christian Rüegg, Gregory Scott Tucker, Nicolas Laflorencie
The dimerized quantum magnet BaCuSi2O6 was proposed as an example of "dimensional reduction" arising near the magnetic-field-induced quantum critical point (QCP) due to perfect geometrical frustration of its interbilayer interactions. We demonstrate by hig ...

Sara Bonella, Alessandro Coretti
The validity of the fluctuation relations (FRs) for systems in a constant magnetic field is investigated. Recently introduced time-reversal symmetries that hold in the presence of static electric and magnetic fields and of deterministic thermostats are use ...
