Application of 57Fe Mössbauer spectroscopy as a tool for mining exploration of bornite (Cu5FeS4) copper ore

Gainov R.; Vagizov F.; Golovanevskiy V.; Ksenofontov V.; Klingelhöfer G.; Klekovkina V.; Shumilova T.; Pen'kov I. (2014)

Nuclear resonance methods, including Mössbauer spectroscopy,are considered as unique techniques suitable for remote on-line mineralogical analysis. The employment of these methods provides potentially significant commercial ...
Crystal field and magnetoelastic interactions in Tb2Ti 2O7

Klekovkina V.; Malkin B. (2014)

In terms of a semiphenomenological exchange charge model, we have obtained estimates of parameters of the crystal field and parameters of the electron-deformation interaction in terbium titanate Tb2Ti 2O7 with a pyrochlore ...
NQR/NMR and Mössbauer spectroscopy of sulfides: Potential and versatility

Gainov R.; Dooglav A.; Vagizov F.; Pen'kov I.; Golovanevskiy V.; Orlova A.; Evlampiev I.; Klekovkina V.; Klingelhöfer G.; Ksenofontov V.; Mozgova N. (2013)

Nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR) and nuclear gamma-resonance (NGR or Mössbauer Effect) methods are generally described as highly sensitive tools in studies of local electronic structure ...
Oxidation and magnetic states of chalcopyrite CuFeS2: A first principles calculation

Klekovkina V.; Gainov R.; Vagizov F.; Dooglav A.; Golovanevskiy V.; Pen'Kov I. (2014)

The ground state band structure, magnetic moments, charges and population numbers of electronic shells of Cu and Fe atoms have been calculated for chalcopyrite CuFeS2 using density functional theory. The comparison between ...
Simulations of magnetic and magnetoelastic properties of Tb 2Ti 2O 7 in paramagnetic phase

Klekovkina V.; Zakirov A.; Malkin B.; Kasatkina L. (2011)

Magnetic and magnetoelastic properties of terbium titanate pyrochlore in paramagnetic phase are simulated. The magnetic field and temperature dependences of magnetization and forced magnetostriction in Tb 2Ti 2O 7 single ...
Structural and magnetic investigations of single-crystalline neodymium zirconate pyrochlore Nd2Zr2 O7

Hatnean M.; Lees M.; Petrenko O.; Keeble D.; Balakrishnan G.; Gutmann M.; Klekovkina V.; Malkin B. (2015)

© 2015 American Physical Society. We report structural and magnetic properties studies of large high-quality single crystals of the frustrated magnet Nd2Zr2O7. Powder x-ray diffraction analysis confirms that Nd2Zr2O7 adopts ...
The Spectral and Magnetic Properties of Er<sup>3+</sup> and Yb<sup>3+</sup> Ions in Y<inf>2</inf>Ti<inf>2</inf>O<inf>7</inf> Crystals with a Pyrochlore Structure

Batulin R.; Cherosov M.; Gil’mutdinov I.; Khaliulin B.; Kiiamov A.; Klekovkina V.; Malkin B.; Mukhamedshin I.; Mumdzhi I.; Nikitin S.; Rodionov A.; Yusupov R. (2019)

© 2019, Pleiades Publishing, Ltd. Abstract: Cubic Y2Ti2O7 single crystals doped with Er3+ or Yb3+ ions have been studied by the methods of electron spin resonance (ESR) and selective laser spectroscopy. ESR spectra exhibit ...
