Doping-induced redistribution of magnetic spectral weight in substituted hexaborides Ce $_{1 - x}$ La $_{x}$ B $_{6}$ and Ce $_{1 - x}$ Nd $_{x}$ B $_{6}$

S. E. Nikitin, P. Y. Portnichenko, A. V. Dukhnenko +6

We investigate the doping-induced changes in the electronic structure of CeB $_{6}$ on a series of substituted Ce $_{1 - x} R_{x}$ B $_{6}$ samples ( $R$ = La, Nd) using diffuse neutron scatteri…

A Local Quantum Phase Transition in YFe $_{2}$ Al $_{10}$

W. J. Gannon, L. S Wu, I. A. Zaliznyak +5

A phase transition occurs when correlated regions of a new phase grow to span the system and the fluctuations within the correlated regions become long-lived. Here we present neutr…

Orphan spins and bound in-gap states in the $S = \frac{5}{2}$ antiferromagnet CaFe $_{2}$ O $_{4}$

C. Stock, E. E. Rodriguez, N. Lee +11

CaFe $_{2}$ O $_{4}$ is an anisotropic $S = \frac{5}{2}$ antiferromagnet with two competing $A$ ( $↑↑↓↓$ ) and $B$ ($\uparrow \downarrow \uparrow \downar…

Evidence for a three-dimensional quantum spin liquid in PbCuTe $_{2}$ O $_{6}$

S. Chillal, Y. Iqbal, H. O. Jeschke +9

The quantum spin liquid (QSL) is a highly entangled magnetic state characterized by the absence of static magnetism in its ground state. Instead, the spins fluctuate in a highly co…

Continuum of quantum fluctuations in a three-dimensional $S = 1$ Heisenberg magnet

K. W. Plumb, Hitesh J. Changlani, A. Scheie +7

Conventional crystalline magnets are characterized by symmetry breaking and normal modes of excitation called magnons with quantized angular momentum $ℏ$ . Neutron scattering co…

Quantum critical singularities in two-dimensional metallic XY ferromagnets

Chandra M. Varma, W. J. Gannon, M. C. Aronson +2

An important problem in contemporary physics concerns quantum-critical fluctuations in metals. A scaling function for the momentum, frequency, temperature and magnetic field depend…

Competing spin density wave, collinear, and helical magnetism in Fe1+xTe

C. Stock, E. E. Rodriguez, P. Bourges +5

The Fe1+xTe phase diagram consists of two distinct magnetic structures with collinear order present at low interstitial iron concentrations and a helical phase at large values of x…

Single-ion properties of the $S_{e f f}$ = 1/2 XY antiferromagnetic pyrochlores, Na $A^{'}$ Co $_{2}$ F $_{7}$ ( $A^{'} =$ Ca $^{2 +}$ , Sr $^{2 +}$ )

K. A. Ross, J. M. Brown, R. J. Cava +4

The antiferromagnetic pyrochlore material NaCaCo $_{2}$ F $_{7}$ is a thermal spin liquid over a broad temperature range (~ 140 K down to $T_{F} = 2.4$ K), in which magnetic correlations be…
