Wide critical fluctuations of the field-induced phase transition in graphite

Christophe Marcenat, Thierry Klein, David LeBoeuf +8

In the immediate vicinity of the critical temperature (T) of a phase transition, there are fluctuations of the order parameter, which reside beyond the mean-field approximation…

Thermal effects versus spin nematicity in a frustrated spin-1/2 chain

M. Pregelj, A. Zorko, D. Arčon +5

The spin-nematic phase is an intriguing state of matter that lacks usual long-range dipolar order, yet it exhibits higher multipolar order. This makes its detection extremely diffi…

Pre-saturation phase in the frustrated ferro-antiferromagnet PbVO(PO)

F. Landolt, S. Bettler, Z. Yan +8

Magnetization, magnetic torque, neutron diffraction and NMR experiments are used to map out the phase diagram of the prototypical quasi-two-dimensional ferro-antiferromag…

Magnetic structure of Cd-doped CeIrIn

K. Beauvois, N. Qureshi, R. Tsunoda +6

We report the magnetic structure of nominally 10% Cd-doped CeIrIn, CeIr(InCd), determined by elastic neutron scattering. Magnetic intensity was observed onl…

Anisotropy of the Upper Critical Field in the Heavy-Fermion Superconductor UTe2 under Pressure

Georg Knebel, Motoi Kimata, Michal Vališka +12

We studied the anisotropy of the superconducting upper critical field in the heavy-fermion superconductor UTe under hydrostatic pressure by magnetoresistivity meas…

Direct determination of the Tomonaga-Luttinger parameter in quasi-one-dimensional spin systems

Mladen Horvatić, Martin Klanjšek, Edmond Orignac

We test the analytical formula for the enhancement of the nuclear magnetic resonance rate by the critical spin fluctuations, over the simple power-law dependence predict…
