Enhancement of the transverse non-reciprocal magneto-optical effect
The origin and properties of the transverse non-reciprocal magneto-optical
(nMO) effect were studied. The transverse nMO effect occurs in the case when
light propagates perpendicularly to the magnetic field. It was demonstrated
that light can experience the transverse nMO effect only when it propagates in
the vicinity of a boundary between two materials and the optical field at least
in one material is evanescent. The transverse nMO effect is pronounced in the
cases of surface plasmons and waveguiding modes. The magnitude of the
transverse nMO effect is comparable to or greater than the magnitude of the
longitudinal nMO effect. In the case of surface plasmons propagating at a
boundary between the transition metal and the dielectric it is possible to
magnify the transverse nMO effect and the magneto-optical figure-of-merit may
increase from a few percents to above 100%. The scalar dispersion relation,
which describes the transverse MO effect in cases of waveguide modes and
surface plasmons propagating in a multilayer MO slab, was derived
Influence of heat treatment on magnetic properties of Cu-Sn-Co-based materials produced by powder metallurgy
In the foundation of this work is the issue for production of non-magnetic materials with
predetermined weak magnetic properties. Preferable solution is to dope these materials with
ferromagnetic impurities in low concentrations. One of the efficient ways to obtain such materials is
the use of powder metallurgy which gives an opportunity to produce complex powder compositions
with variety of components in precisely specified concentrations
Drift of domain walls in a harmonic magnetic field
It is shown that a two-step form of the dynamic magnetization curve (and the hysteresis loop) established for a multiaxial ferrite-garnet wafer with a low quality factor (Q < 1) and considerable anisotropy in the plane (K p /K u = 14) in the frequency range of 25-1000 Hz is explained by the reconstruction of the dynamic domain structure, particularly by the established features of the drift of domain boundaries in the harmonic magnetic field. © 2013 Allerton Press, Inc
Evidence of phi --> pi0 pi0 gamma and phi --> pi0 eta gamma decays in SND experiment at VEPP-2M
Preliminary results on the study of e+e- --> phi(1020) --> pi0 pi0 gamma, eta
pi0 gamma processes from SND experiment at VEPP-2M collider in Novosibirsk are
presented. Branching ratios of rare radiative phi --> pi0 pi0 gamma and phi -->
pi0 eta gamma decays are measured:
B(phi --> pi0 pi0 gamma ) = (1.1 +- 0.2) * 10^-4
(invariant mass (pi0 pi0) < 800 MeV),
B(phi --> eta pi0 gamma ) = (1.3 +- 0.5) * 10^-4.Comment: Talk at the HADRON97 conference, BNL, Aug 24-30 1997; LaTeX, 4 pages,
