    TRACE INTERPOLATION BY SLANT-STACK MIGRATION (1990)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The slant-stack migration formula based on the Radon transform is studied with respect to the depth step Δz of wavefield extrapolation. It can be viewed as a generalized trace-interpolation procedure including wave extrapolation with an arbitrary step Δz. For Δz= 0 the formula yields the familiar plane-wave decomposition, while for Δz 〉 0 it provides a robust tool for migration transformation of spatially undersampled wavefields. Using the stationary phase method, it is shown that the slant-stack migration formula degenerates into the Rayleigh-Sommerfeld integral in the far-field approximation. Consequently, even a narrow slant-stack gather applied before the diffraction stack can significantly improve the representation of noisy data in the wavefield extrapolation process. The theory is applied to synthetic and field data to perform trace interpolation and dip reject filtration. The data examples presented prove that the Radon interpolator works well in the dip range, including waves with mutual stepouts smaller than half the dominant period.

    Response of a kinetic Ising system to oscillating external fields: Amplitude and frequency dependence : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: The S=1/2, nearest-neighbor, kinetic Ising model has been used to model magnetization switching in nanoscale ferromagnets. For this model, earlier work based on the droplet theory of the decay of metastable phases and Monte Carlo simulations has shown the existence of a size dependent spinodal field which separates deterministic and stochastic decay regimes. We extend the above work to study the effects of an oscillating field on the magnetization response of the kinetic Ising model. We compute the power spectral density of the time-dependent magnetization for different values of the amplitude and frequency of the external field, using Monte Carlo simulation data. We also investigate the amplitude and frequency dependence of the probability distributions for the hysteresis loop area and the period-averaged magnetization. The time-dependent response of the system is classified by analyzing the behavior of these quantities within the framework of the distinct deterministic and stochastic decay modes mentioned above. © 1996 American Institute of Physics.

    The Ising model between one and two dimensions (1988)

    Notes: A method which continuously interpolates between one and two dimensions for any magnetic model on a square lattice is introduced. This interpolation scheme, which preserves the translational invariance of the lattice, can be performed for any Hamiltonian with pairwise interactions. The Potts model interpolated between one and two dimensions is studied using finite-size scaling of data obtained with a Monte Carlo method.

    Notes: Three theorems dealing with transfer matrices in statistical mechanical systems are proved. The theorems state that the nonzero eigenvalues of transfer matrices formed through various prescriptions are identical. Hence it is possible to ascribe a physical meaning to all the eigenvalues of a transfer matrix, not just to the few largest eigenvalues. The first theorem states that the transfer matrix formed by building a system M layers at a time has as its only nonzero eigenvalues the eigenvalues of the transfer matrix formed by building the M layers of the system one at a time. This theorem relates the product of two nM×nM M-layer transfer matrices to the product of M one-layer M×M transfer matrices. The second theorem states that one of the nM×nM M-layer transfer matrices (for M〉1) has only one nonzero eigenvalue. A procedure for finding this eigenvalue and all eigenvectors is given. The third theorem generalizes the first to the case where the chosen layering is not an integer multiple of the interaction length.

    FeTAC, a chainlike metamagnet (1985)

    Notes: Single crystal susceptibility, magnetization and powder Mössbauer spectroscopy measurements are reported for [(CH3)3NH]FeCl3 ⋅ 2H2O, FeTAC. Powder x-ray studies show this compound to be isomorphous to previously studied one-dimensional compounds. The low-temperature susceptibilities are highly anisotropic with the greatest susceptibility along the chain (b) axis. Antiferromagnetic ordering is observed in both the susceptibility data and the Mössbauer spectra near 3.2 K. Metamagnetic transitions occur when small fields (less than 200 Oe) are applied parallel to the b axis. The data are interpreted in terms of a model of antiferromagnetic Ising-like chains aligned along the a axis while canted towards b. Results of a molecular field model for weakly coupled Ising chains are also presented.
