Change in the sign of the Kerr effect in ion-beam-synthesized Fe3Si films

Chirkov V.; Gumarov G.; Petukhov V.; Valeev V.; Denisov A. (2014)

Ion-beam-synthesized Fe3Si thin films are studied using the magneto-optical Kerr effect, ferro-magnetic resonance, electron diffraction, and Auger spectroscopy. A change in the direction of rotation of the plane-polarized ...
Diffusion-limited aggregation at multiple centers: Model of dendrite growth at ion beam synthesis of magnetic films in external field

Balakirev N.; Gumarov G.; Zhikharev V.; Petukhov V. (2011)

Computer simulations are used to generate two-dimensional dendrites from atoms carrying magnetic moment being parallel to the external magnetic field. The numerical model is based on the model of diffusion-limited aggregation ...
Investigation of strain-induced magnetization change in ferromagnetic microparticles

Chuklanov A.; Nurgazizov N.; Bizyaev D.; Khanipov T.; Bukharaev A.; Yu Petukhov V.; Chirkov V.; Gumarov G. (2016)

This work is devoted to investigation of magnetoelastic strain effect on the ferromagnetic microparticles of permalloy. An original method of sample fabrication with compressed microparticles is proposed. Magnetic force ...
MOKE investigation of silicide films ion-beam synthesized in single-crystal silicon

Gumarov G.; Petukhov V.; Gumarov A.; Khalikov R.; Konovalov D.; Valeev V.; Khaibullin R. (2012)

Magnetic-field-assisted ion-beam synthesis was used to produce thin magnetic films. Si wafers were implanted with 40 keV Fe + ions with a fluence of 3 × 10 17 cm -2 in the external magnetic field of 9.6 × 10 4 A/m. The ...
Peculiarities of x-ray fluorescent definition of ion-implanted Fe in Si single crystals

Khusnullin N.; Ivoilov N.; Batalov R.; Bayazitov R.; Gumarov G. (2005)

The technique of definition of iron concentration in a surface layer of Si(100) is developed by use of spectrometer Spectroscan-U. The measurements of intensity of X-ray fluorescent line FeKα as a function of turn of initial ...
Scanning MOKE investigation of ion-beam-synthesized silicide films

Gumarov G.; Konovalov D.; Alekseev A.; Petukhov V.; Zhikharev V.; Nuzhdin V.; Shustov V. (2012)

Fe ions with an energy of 40 keV were implanted into Si plates with the fluence varying in the range of (1.6-3.0) × 10 17 ion/cm 2 in the external magnetic field. Scanning magnetooptical Kerr effect (MOKE) studies have ...
Spectral ellipsometry of cobalt-ions implanted silicon surface

Bazarov V.; Valeev V.; Nuzhdin V.; Osin Y.; Gumarov G.; Stepanov A. (2015)

© (2015) Trans Tech Publications, Switzerland. Monocrystalline silicon wafers implanted by cobalt ions with energy of 40 keV at a fluence range from 6.6×1012 to 2.5×1017 Co+-ion/cm2 were investigated by optical spectroscopic ...
Study of morphology, magnetic properties, and visible magnetic circular dichroism of Ni nanoparticles synthesized in SiO2 by ion implantation

Edelman I.; Petrov D.; Ivantsov R.; Zharkov S.; Velikanov D.; Gumarov G.; Nuzhdin V.; Valeev V.; Stepanov A. (2013)

A systematic study of ensembles of nickel nanoparticles fabricated by Ni+-ion implantation at a dose of (0.5-1.0)×1017 ions/cm2 in a thin near-surface layer of an amorphous SiO2 matrix by means of transmission electron ...
