Brillouin scattering in FeSi/X/FeSi double-layer films, X=ZnO and SiO2

Journal of Applied Physics, 1990
Thermally-excited spin waves in double-layer films of FeSi/X/FeSi (where X=ZnO and SiO2) have been studied by Brillouin scattering. The thickness of the FeSi (2.6 wt. % of Si) layers is fixed at 1100±30 Å. Scattering from the Damon-Eshbach-type surface wave and the standing spin waves has been observed.

Paramagnetic Excited State of FeSi

Physical Review, 1967
The anomalous behavior of the temperature dependence of the susceptibility and specific heat of the intermetallic compound FeSi is reexamined from both an experimental and a theoretical point of view. It is shown that a consistent set of experimental data is obtained below a temperature of about 700\ifmmode^\circ\else\textdegree\fi{}K.

FORMATION OF EPITAXIAL GAMMA-FESI(2) AND BETA-FESI(2) LAYERS ON (111) SI

1994
Polycrystalline beta-FeSi2 layers, 85 nm thick, thermally grown on (111) Si substrates have been irradiated by 25 ns ruby-laser pulses in the energy density range 0.4-1.2 J/cm2. Formation of the epitaxial metastable gamma-FeSi2 has been observed in a selected energy density range. The stability of gamma-FeSi2 has been tested by annealing in the 300-800-

Spin-fluctuation theory of FeSi

Journal of Physics: Condensed Matter, 1997
The temperature dependence of the magnetic susceptibility of FeSi is calculated over a wide temperature range on the basis of spin-fluctuation theory applied to a model of an exchange-enhanced semiconductor. We can reproduce the low-temperature activation-type behaviour of the susceptibility as well as the Curie - Weiss behaviour observed at high ...

Theory of magnetization process of FeSi

Journal of Physics: Condensed Matter, 1998
We give a new theoretical explanation to the magnetization process of FeSi based on the spin fluctuation theory without assuming the negative mode - mode coupling mechanism previously proposed to explain the anomalous magnetic properties of this compound.
