Electron spin as a spectrometer of nuclear spin noise and other fluctuations
This chapter describes the relationship between low frequency noise and
coherence decay of localized spins in semiconductors. Section 2 establishes a
direct relationship between an arbitrary noise spectral function and spin
coherence as measured by a number of pulse spin resonance sequences. Section 3
describes the electron-nuclear spin Hamiltonian, including isotropic and
anisotropic hyperfine interactions, inter-nuclear dipolar interactions, and the
effective Hamiltonian for nuclear-nuclear coupling mediated by the electron
spin hyperfine interaction. Section 4 describes a microscopic calculation of
the nuclear spin noise spectrum arising due to nuclear spin dipolar flip-flops
with quasiparticle broadening included. Section 5 compares our explicit
numerical results to electron spin echo decay experiments for phosphorus doped
silicon in natural and nuclear spin enriched samples.Comment: Book chapter in "Electron spin resonance and related phenomena in low

Strzeleckia major n. g., n. sp. and S. minor n. sp. (Digenea: Hasstilesiidae) from Antechinus swainsonii (Marsupialia: Dasyuridae) in Australia
Strzeleckia major n. g., n. sp. and S. minor n. sp. are described from the dusky antechinus Antechinus swainsonii (Marsupialia: Dasyuridae) from the Kosciusko National Park in southern New South Wales, Australia. The two species were found together in the same individual host animals but occupy different sites in the intestine. The new genus is placed within the Hasstilesiidae, where it differs from the only other genus, Hasstilesia, by being more elongate and in having larger suckers, tandem testes, the ovary between rather than opposite the testes, and in having the caeca not reaching the posterior end of the body. It is suggested that the life-cycles of these species are similar to those of other hasstilesiids. Pupillid snails may act as sole intermediate hosts
