Observation of Quantum Oscillations in The Low Temperature Specific Heat of SmB
P. G. LaBarre, A. Rydh, J. Palmer-Fortune +4
We report measurements of the low-temperature specific heat of Al-flux-grown samples of SmB in magnetic fields up to 32 T. Quantum oscillations periodic in are observed b…
Eminuscent phase in frustrated magnets: a challenge to quantum spin liquids
S. V. Syzranov, A. P. Ramirez
A geometrically frustrated (GF) magnet consists of localised magnetic moments, spins, whose orientation cannot be arranged to simultaneously minimise their interaction energies. Su…
Extremely Weakly Interacting and Excitations and Evidence for Fractional Quantization in a Magnetization Plateau: CeSb
Patrick G. LaBarre, Brinda Kuthanazhi, Caiden Abel +2
The plateau at 1/3 of the saturation magnetization, , in the metamagnet CeSb is accompanied by a state of ferromagnetic layers of spins in an up-up-down sequence. We measured…
A Néel-type antiferromagnetic order in the spin 1/2 rare-earth honeycomb YbCl
Jie Xing, Erxi Feng, Yaohua Liu +8
Most of the searches for Kitaev materials deal with magnets with spin-orbit-coupled local moments such as iridates and -RuCl. Here we propose the monoclini…
Degeneracy of the 1/8 plateau and antiferromagnetic phases in the Shastry-Sutherland magnet TmB4
Jennifer Trinh, Sreemanta Mitra, Christos Panagopoulos +3
The 1/8 fractional plateau phase (1/8-FPP) in Shastry-Sutherland Lattice (SSL) spin systems has been viewed an exemplar of emergence on an Archimedean lattice. Here we explore this…
Implications of the Measured Angular Anisotropy at the Hidden Order Transition of URu2Si2
Premala Chandra, Piers Coleman, Rebecca Flint +2
The heavy fermion compound URu2Si2 continues to attract great interest due to the long- unidentified nature of the hidden order that develops below 17.5K. Here we discuss the impli…
