  • EPR study of polycrystalline superconductors with YBa2Cu3O7 structure 
    Alekseevskii N.; Mitin A.; Nizhankovskii V.; Garifullin I.; Garif'yanov N.; Khaliullin G.; Khylbov E.; Kochelaev B.; Tagirov L. (1989)
    Electron paramagnetic resonance (EPR) of Gd3+, Eu2+, and copper ions has been investigated in the high-Tc superconductor with YBa2Cu3O7-α structure. It has been established that the system is heterogeneous at 0.15≤δ≤0.5 ...
  • FMR studies of magnetic properties of Co and Fe thin films on Al 2O3 and MgO substrates 
    Goryunov Y.; Khaliullin G.; Garifullin I.; Tagirov L.; Schreiber F.; Bödeker P.; Bröhl K.; Morawe C.; Mühge T.; Zabel H. (1994)
    The effect of substrates on the magnetic properties has been studied for Co and Fe films both on Al2O3 (112̄0) and MgO (001) substrates by using ferromagnetic resonance techniques. For Fe(001)/MgO(001) samples the thickness ...
  • Homogeneous NMR line shift induced by magnetic doping in a superconductor 
    Khaliullin G.; Tagirov L. (1982)
    It is shown theoretically that a uniform conduction electron spin polarization, induced by magnetic doping, arises in a superconducting state. Measurements of the corresponding Knight shift enable one to determine the sign ...
  • Magnetic anisotropies of sputtered Fe films on MgO substrates 
    Goryunov Y.; Garifyanov N.; Khaliullin G.; Garifullin I.; Tagirov L.; Schreiber F.; Mühge T.; Zabel H. (1995)
    Ferromagnetic resonance (FMR) and superconducting quantum interference device (SQUID) measurements have been used to study the magnetic properties of rf sputtered Fe films on MgO(001) substrates. The dependences of the FMR ...
  • Possible origin for oscillatory superconducting transition temperature in superconductor/ferromagnet multilayers 
    Mühge T.; Garif'yanov N.; Goryunov Y.; Khaliullin G.; Tagirov L.; Westerholt K.; Garifullin I.; Zabel H. (1996)
    We have studied superconducting and magnetic properties of sputtered Fe/Nb/Fe trilayers. For a fixed Nb thickness and with changing Fe thickness, dFe, a nonmonotonic behavior of the superconducting transition temperature ...
  • Spin-wave excitations of paramagnetic impurities in superconductors 
    Khaliullin G.; Kochelaev B. (1984)
    The existence of spin-wave excitations of paramagnetic impurities in a superconductor in an external magnetic field due to the long-range exchange interactions is predicted. The damping has been calculated and possible ...
  • Superconducting and magnetic properties of epitaxial high-quality Fe/Nb bilayers 
    Mühge T.; Zoller I.; Westerholt K.; Zabel H.; Garif'yanov N.; Goryunov Y.; Garifullin I.; Khaliullin G.; Tagirov L. (1997)
    Single crystal Fe/Nb (110) bilayers with an Nb thickness d Nb in the range from 140 to 650 Å and with an Fe thickness d Fe in the range from 5 to 100 Å were prepared using molecular beam epitaxy (MBE) techniques. For d ...
