Description

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract The stochastic hyperfine interactions modeling library (SHIML) provides a set of routines to assist in the development and application of stochastic models of hyperfine interactions. The library provides routines written in the C programming language that (1) read a text description of a model for fluctuating hyperfine fields, (2) set up the Blume matrix, upon which the evolution operator of the system depends, and (3) find the eigenvalues and eigenvectors of the Blume matrix so that theoreti... Title of program: SHIML Catalogue Id: AEIF_v2_0 Nature of problem In condensed matter systems, hyperfine methods such as nuclear magnetic resonance (NMR), Mössbauer effect (ME), muon spin rotation (ΜSR), and perturbed angular correlation spectroscopy (PAC) measure electromagnetic fields due to electronic and magnetic structure within Angstroms of nuclear probes through the hyperfine interaction. When interactions fluctuate at rates comparable to the time scale of a hyperfine method, there is a loss in signal coherence, and spectra in the time domain are damped ...
