  • EPR study on higher oxygen pressure synthesized compound Pr2-xGdxCuO4 
    Ivanshin V.; Mamin G.; Shengelaya A.; Keller H.; Klamut P.; Sikora A. (1999)
    The electron paramagnetic resonance (EPR) and magnetic susceptibility measurements were performed in Pr2-xGdxCuO4 (x = 0.02; 0.05) annealed at the higher oxygen pressures of 15 and 21 bar. This annealing treatment causes ...
  • ESR bottleneck effect in the heavy-fermion metal YbRh2Si2 
    Ivanshin V. (2007)
    An approach related to the bottleneck effect is proposed for an origin of the electron spin resonance (ESR) of a Kondo ion (Yb3+) in the undoped Kondo-lattice systems YbRh2Si2 and YbIr2Si2. The effects observed for the ...

    Ivanshin V.; Deisenhofer J.; Krug Von Nidda H.; Loidl A.; Mukhin A.; Balbashov A.; Eremin M. (2000)
    We present a systematic electron-spin-resonance (ESR) study in single crystals of La1-xSrxMnO3(0≤x ≤0.2). The temperature dependence of the ESR linewidth marks all significant transitions between both orthorhombic (O′,O) ...
  • ESR study of spin dynamics in the ternary phosphide YbRh 6P 4 
    Ivanshin V.; Gataullin E.; Sukhanov A. (2011)
    We have used electron spin resonance (ESR) to investigate the YbRh 6P 4 powder samples. It is shown that the exotic ESR absorption is caused here by hybridization effects between the Yb 4 f-orbitals and the wave functions ...

    Ivanshin V.; Yushankhai V.; Sichelschmidt J.; Zakharov D.; Kaul E.; Geibel C. (2003)
    The chainlike spin-1/2 antiferromagnetic vanadium oxide compound Sr 2V3O9 is studied by electron spin resonance (ESR) with special attention to the space distribution of the Dzyaloshinskii-Moriya (DM) vector along magnetic ...
  • ESR study of the undoped heavy-fermion compound YbRh2Si 2 
    Ivanshin V.; Zverev D. (2004)
    The electron spin resonance (ESR) of the heavy-fermion metal YbRh 2Si2 has been studied. The angular variation and the temperature dependence of the ESR line width have been measured in YbRh 2Si2 single crystals in the ...
  • Evolution of the 4f electron localization from YbRh2Si 2 to YbRh2Pb studied by electron spin resonance 
    Ivanshin V.; Litvinova T.; Ivanshin N.; Pöppl A.; Sokolov D.; Aronson M. (2014)
    We report on electron spin resonance (ESR) experiments on the Heusler alloy YbRh2Pb and compare its spin dynamics with that of several other Yb-based intermetallics. A detailed analysis of the derived ESR parameters indicates ...
  • Griffiths phases vs magnetic polarons in the lightly doped La1-xSrxMno3 
    Ivanshin V.; Deisenhofer J.; Krug von Nidda H.; Loidl A. (2007)
    The nature of the ferromagnetic (FM)-paramagnetic (PM) transition in perovskite-doped manganites is the subject of considerable discussions. There is no general consensus about the microscopic physics of stable FM clusters ...
  • Hybridized electronic states in dense intermetallics as studied by ESR 
    Ivanshin V.; Litvinova T.; Sukhanov A.; Ivanshin N.; Endeward B. (2011)
    We review electron spin resonance (ESR) experiments in several concentrated Yb-, Ce-, and Eubased intermetallic systems. Recent theoretical studies attribute well resolved ESR signals with hybridization effects between 4f ...
  • Low Temperature Electron Spin Resonance of the Kondo Ion in a Heavy Fermion Metal: YbRh2Si2 
    Sichelschmidt J.; Ivanshin V.; Ferstl J.; Geibel C.; Steglich F. (2003)
    The electron spin resonance (ESR) study on single crystals of the heavy fermion metal YbRh2Si2 was presented. The study showed non-Fermi liquid behavior related to a close antiferromagnetic quantum critical point. It was ...

    Ivanshin V.; Gataullin E.; Sukhanov A.; Ivanshin N.; Rojas D.; Fernández Barquín L. (2017)
    © 2017, Pleiades Publishing, Ltd.Variations in magnetic properties of the heavy-fermion YbNi2 alloy when milled in a high energy ball milling system have been investigated. The ferromagnetic transition (TC = 10.4 K) in the ...
  • Microscopic State of Low Doped Manganites la1-xSrx MnO3 Probed by ESR 
    Ivanshin V.; Eremin M.; Deisenhofer J.; Von Krug Nidda H.; Loidl A.; Eremina R. (2002)
    The electron spin resonance (ESR) measurements were performed in single crystals of La1-xSrxMnO3 (0.05 < x < 0.125) in order to study the interplay of crystal field, Dzyaloshinsky-Moriya interaction, Jahn-Teller (JT) effect, ...

    Ivanshin V.; Schauwecker R.; Warden M.; Erhart P.; Keller H.; Guentherodt H.; Lang H.; Thommen-Geiser V. (1996)
    Methods of electron-spin resonance (ESR) and direct, non-linear field-modulated microwave absorption (FMMA) were applied for the measurements in low-and high-purity samples of rubidium-doped fullerene, Rb3C60. The coexistence ...

    Warden M.; Ivanshin V.; Erhart P. (1994)
    Nonlinear, field-modulated, direct microwave absorption (FMMA) was observed in copper-free Ba1-xKxBiO3 powder samples. The high-field, low-temperature results were compared to previous measurements of YBa CuO and BiSrCaCuO. ...
