Zeeman split Kramers doublets in spin-supersolid candidate NaBaCo(PO)
T. I. Popescu, N. Gora, F. Demmel +6
NaBaCo(PO) is a triangular antiferromagnet that displays highly efficient adiabatic demagnetization cooling (J. Xiang Nature , 270 (…
Anomalous spin-waves and the commensurate-incommensurate magnetic phase transition in LiNiPO4
T. B. S. Jensen, N. B. Christensen, M. Kenzelmann +9
Detailed spin-wave spectra of magneto-electric LiNiPO4 have been measured by neutron scattering at low temperatures in the commensurate (C) antiferromagnetic (AF) phase with orderi…
Solitary magnons in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +10
CaFeO is a anisotropic antiferromagnet based upon zig-zag chains having two competing magnetic structures, denoted as the A ($\uparrow \uparrow \downarro…
Short-range dynamics in the solid and liquid phases
E. I. Andritsos, M. T. Dove, F. Demmel +1
The existence of the phonon-roton minimum has been widely observed for both the solid and liquid phases but so far there is no sufficient theoretical explanation of its origin. In…
Effect of carrier doping on the formation and collapse of magnetic polarons in lightly hole-doped La_{1-x}Sr_xCoO_3
A. Podlesnyak, G. Ehlers, M. Frontzek +7
We investigate the doping dependence of the nanoscale electronic and magnetic inhomogeneities in the hole-doping range 0.002<x<0.1 of cobalt based perovskites, La{1-x}Sr_xCoO_3. Us…
The effect of substitution of Mn for Ni on the magnetic and transport properties of CeNi0.8-xMnxBi2
Soo-Whan Kim, Kyu Joon Lee, D. T. Adroja +3
We report the results of Mn substitution for Ni in CeNi0.8Bi2, (i.e. CeNi0.8-xMnxBi2). All the samples have an antiferromagnetic ordered state below TN = 5.0 K due to localized 4f-…
