Impact of further-range exchange and cubic anisotropy on magnetic excitations in the fcc kagome antiferromagnet IrMn3
Autor: Martin L. Plumer, J. P. Whitehead, M. D. Leblanc, S. E. Nagler, B. W. Southern, Garrett E. Granroth, Jiaqiang Yan, Adam A. Aczel
Exchange interactions up to fourth nearest neighbor are shown within a classical local-moment Heisenberg approach to be important to model inelastic neutron scattering data on the fcc kagome antiferromagnet IrMn$_3$. Spin wave frequencies are calcula

Spin waves in the anisotropic fcc kagome antiferromagnet
Autor: B. W. Southern, Martin L. Plumer, M. D. Leblanc, J. P. Whitehead
Spin wave calculations demonstrate that the macroscopic continuous degeneracy associated with the two-dimensional kagome Heisenberg spin lattice persists in the case of the stacked fcc structure giving rise to zero energy modes in three dimensions. T

Monte Carlo simulations of intragrain spin effects in a quasi-2D Heisenberg model with uniaxial anisotropy
Autor: J. P. Whitehead, M. D. Leblanc, Martin L. Plumer
Publikováno v: Journal of physics. Condensed matter : an Institute of Physics journal. 25(19)
A combination of Metropolis and modified Wolff cluster algorithms is used to examine the impact of uniaxial single-ion anisotropy on the phase transition to ferromagnetic order of Heisenberg macrospins on a 2D square lattice. This forms the basis of

Kinetic Monte Carlo approach to modeling thermal decay in perpendicular recording media
Autor: Martin L. Plumer, J. van Ek, J. P. Whitehead, T. J. Fal, M. D. Leblanc, J. I. Mercer
Publikováno v: Physical Review B. 87
A procedure is developed to study the evolution of high anisotropy magnetic recording media due to thermally activated grain reversal. It is assumed that the system is composed of single domain grains that evolves by passing through a sequence of rel

Certification of Marine Sediment Reference Materials for PAHs
Autor: J. M. Curtis, R. K. Boyd, P. G. Sim, S. M. Crain, J. Macdonald, D. Thomas, G. M. McCully, M. D. Leblanc
Publikováno v: Polycyclic Aromatic Compounds. 9:217-224
The Marine Analytical Chemistry Standards Program (MACSP) of the National Research Council of Canada produces certified reference materials for several analytes, including PAHs, in marine matrices. Four harbour sediment CRMs are available, HS-3,4,5,

Micromagnetic simulations of sweep-rate dependent coercivity in perpendicular recording media
Autor: J. P. Whitehead, J. van Ek, M. D. Leblanc, Martin L. Plumer
The results of micromagnetic simulations are presented which examine the impact of thermal fluctuations on sweep rate dependent coercivities of both single-layer and exchange-coupled-composite (ECC) perpendicular magnetic recording media. M-H loops a

Transition temperature and magnetic properties of the granular Ising model in two dimensions studied by Monte Carlo simulations: Impact of intragrain spin structure
Autor: J. P. Whitehead, M. D. Leblanc, J. I. Mercer, Martin L. Plumer
Publikováno v: Physical Review B. 82
Monte Carlo simulations are performed on a stacked square lattice model of weakly interacting magnetic grains composed of Ising spins. The role of intragrain spin structure on thermal properties are investigated in this simple representation of granu

Determination of erythromycin A in salmon tissue by liquid chromatography with ionspray mass spectrometry
Autor: M R Bailey, K McErlane, Michael A. Quilliam, S. Pleasance, D D Kitts, M D LeBlanc, Robert K. Boyd, David H. North, J Kelly
A reverse-phase liquid chromatography/mass spectrometry (LC/MS) method, incorporating gradient elution, is described for the characterization of residual erythromycin A and its metabolites in salmon tissue. The method uses ion-spray, a mild atmospher
