Pulsed NMRON oscillatory free induction decay signals in the angular distribution of gamma radiation from plated60Co Fe
Results for an inhomogeneously broadened60Co Fe NMRON sample have been obtained for gamma detected single pulse (nutation) and two pulse (free induction decay) experiments in the region of intermediate-to-low R(=ω1/Δ). Here ω1 is the angular frequency measure of the strength of the ferromagnetically enhanced RF field at the nucleus and Δ is the HWHM of the inhomogeneously broadened line. Comparisons of the oscillatory FID signals obtained are made with the theoretical predictions of the following paper [6]. © 1993 J.C. Baltzer AG, Science Publishers
Effect of Secondary Echo Signals in Spin-Systems with a Large Inhomogeneous Broadening of NMR Line
The possibility of comparatively simple and fast determination of
characteristic relaxation parameters T1, T2 and T3 for nuclear spin-systems
with strong Larmor and Rabi inhomogeneous broadenings of NMR lines using the
secondary echo signal effect was experimentally shown. Resides, this method
gives opportunity to obtain a valuable infomation on the inhomogeneous NMR
broadening which reflects the character of magnetic field microscopic
destribution in such systems, as example, multidomain magnetics and
superconductors.Comment: 12 pages, 5 figure
Two-pulse stimulated echo in magnets
The results of experimental study of two-pulse stimulated echo in
ferromagnets of two types are presented. Ferromagnet Co and half-metal Co MnSi
2, in which a single-pulse echo formed by the distortion mechanism of the
fronts of exciting pulse is also observed, are classified among the first type.
Lithium ferrite and intermetal compound MnSb characterized by the absence of
single-pulse echo in them - belong to the second type. For signals of two-pulse
stimulated echo in the materials of the first type a short time and a long time
of relaxations are observed. The short time is about the order of value shorter
less than the spin-spin relaxation time. The long time is close to the
transverse relaxation time of single-pulse echo formed by the distortion
mechanism. The mechanisms that provide the possible interpretations of the
peculiarities of the processes of nuclear magnetic relaxation are discussed.Comment: 10 pages, 7 figure
