Spin freezing and dynamics in Ca_{3}Co_{2-x}Mn_{x}O_{6} (x ~ 0.95) investigated with implanted muons: disorder in the anisotropic next-nearest neighbor Ising model
T. Lancaster, S. J. Blundell, P. J. Baker +5
We present a muon-spin relaxation investigation of the Ising chain magnet Ca_{3}Co_{2-x}Mn_{x}O_{6} (x~0.95). We find dynamic spin fluctuations persisting down to the lowest measur…
Determination of characteristic muon precession and relaxation signals in FeAs and FeAs2, possible impurity phases in pnictide superconductors
P. J. Baker, H. J. Lewtas, S. J. Blundell +5
We report muon-spin relaxation measurements of highly homogeneous samples of FeAs and FeAs2, both previously found as impurity phases in some samples of recently synthesized pnicti…
Effect of magnesium doping on the orbital and magnetic order in LiNiO2
M. Bonda, M. Hopzapfel, Sophie De Brion +6
In LiNiO2, the Ni3+ ions, with S=1/2 and twofold orbital degeneracy, are arranged on a trian- gular lattice. Using muon spin relaxation (MuSR) and electron spin resonance (ESR), we…
Isotope effect in quasi-two-dimensional metal-organic antiferromagnets
P. A. Goddard, J. Singleton, C. Maitland +9
Although the isotope effect in superconducting materials is well-documented, changes in the magnetic properties of antiferromagnets due to isotopic substitution are seldom discusse…
The kagome staircase compounds NiVO and CoVO studied with implanted muons
T. Lancaster, S. J. Blundell, P. J. Baker +3
We present the results of muon-spin relaxation (SR) measurements on the kagome staircase compounds NiVO and CoVO. The magnetic behavior o…
Magnetism in Geometrically Frustrated YMnO3 Under Hydrostatic Pressure Studied with Implanted Muons
T. Lancaster, S. J. Blundell, D. Andreica +10
The rare-earth ferroelectromagnet YMnO3 consists of weakly coupled triangular layers of S=2 spins. Below T_N ~ 70 K muon-spin relaxation data show two oscillatory relaxing signals…
