Solid state- and magneto-chemistry of the SrO-Fe2O3 system : III. The non-existence of single-phase "SrFe2O4"
(Elsevier, 1979-11)
A detailed Mossbauer investigation of 1 : 1 SrO : Fe2O3 has shown that a single phase with the SrFe2O4 composition does not exist in the SrO-Fe2O3 system when SrCo3 and Fe2O3 are reacted in air. A multiphase assemblage of ...
A new technique of incoherent complex signal detection
(Elsevier, 1978-10)
A new technique of incoherent complex spatial filtering is presented. The advantage of this technique is its use of white light, for which the unavoidable coherent noise in the coherent optical processor may be removed. ...
2D heteronuclear NMR measurements of spin-lattice relaxation times in the rotating frame of X nuclei in heteronuclear HX spin systems
(Elsevier, 1991-08)
Theoretical and experimental aspects of T1p are discussed for a heteronuclear HX two-spin system (T1pX) where only the X nucleus is spin-locked. An expression for T1pX in terms of spectral density functions and the effective ...
Electron spectra of heavy-fermion systems
(Elsevier, 1988-12-02)
An overview is presented of current understanding and recent approaches and issues in studies of the single-particle electron spectra of heavy-fermion materials, with emphasis on uranium compounds.
Modular optics interferometer
(Elsevier, 1977-06)
A waveguide interferometer is assembled using holographically formed optical elements that are constructed as individual components and can be selectively attached to an optical waveguide. The interferometer is very rugged ...
Analytic MODFET models beyond the triangular well approximation
(Elsevier, 1990-07)
A new approach to modeling normal interface modulation doped field-effect transistors (MODFETs) is presented in which the 2-D electron gas density is integrated along the channel instead of the channel potential. With this ...
Triplet state EPR spectra
(Elsevier, 1984-03)
A characterization of triplet EPR spectra in terms of the eight phenomenological parameters of the spin Hamiltonian is given. Closed-form solutions for the three possible resonant fields between triplet energy levels are ...
