For single crystals HgCr2Se4 doped by nonmagnetic Cu, Au and Ga ions and single crystals of HgCr2Se4 matrix growing in different synthesis conditions both the dc and ac magnetic susceptibility as well as the magnetization have been measured. As it follows from the analysis of the obtained results, paradoxically, the dopants strengthen the long range magnetic interactions of the ferromagneticall...

We systematically measured the dc voltage V(ISH) induced by spin pumping together with the inverse spin Hall effect in ferromagnet-platinum bilayer films. In all our samples, comprising ferromagnetic 3d transition metals, Heusler compounds, ferrite spinel oxides, and magnetic semiconductors, V(ISH) invariably has the same polarity, and scales with the magnetization precession cone angle. These ...

We show that in a quantum wire the effective spin-orbit-induced internal magnetic field leads to a narrow spin-flip resonance at low temperatures in the absence of an applied magnetic field. An applied dc magnetic field perpendicular to and small compared with the spin-orbit field enhances the resonance absorption by several orders of magnitude. The component of the applied field parallel to th...

We report the electrical detection of magnetization dynamics in an Al/AlOx/Ni80Fe20/Cu tunnel junction, where a Ni80Fe20 ferromagnetic layer is brought into precession under ferromagnetic resonance conditions. The dc voltage generated across the junction by the precessing ferromagnet is enhanced about an order of magnitude compared to the voltage signal observed when the contacts in this type o...

We report the experimental observation of room-temperature perpendicular magnetic anisotropy in Ni/Pt multilayers having 7–26 Å Ni and 2.3–4.6 Å Pt layer thicknesses, prepared by dc magnetron sputtering on glass substrates at 7 mTorr Ar sputtering pressure. Perpendicular magnetic anisotropy was found to be sensitively dependent on both Niand Pt-layer thicknesses, and a maximum anisotropy energy...

Three isostructural 1D lanthanoid complexes with the general formula {[Ln2(DTE)(HDTE)(MeOH)2] ̈ 2H2O}n (Ln = Tb, Dy, and Yb; DTE = 1,2-bis(5-carboxyl-2-methyl-3-thienyl) perfluorocyclopentene) were synthesized. In the 1D chain structure of each complex, lanthanide ions are seven coordinate with a capped trigonal prism geometry. The 1,2-bis(5-carboxyl-2-methyl3-thienyl) perfluorocyclopentene (DTE...

Non-equilibrium dynamics in a Ag(Mn) spin glass are investigated by measurements of the temperature dependence of the remanent magnetization. Using specific cooling protocols before recording the thermo-or isothermal remanent magnetizations on reheating , it is found that the measured curves effectively disclose non-equilibrium spin glass characteristics such as aging and memory phenomena as we...

We observed unexpected resonant response in [Fe/Cr]10 multilayers epitaxially grown on MgO(100) substrates which exists only when both ac current and dc magnetic field are simultaneously applied. The magnitude of the resonances is determined by the multilayer magnetization proving their intrinsic character. The reduction of interface epitaxy leads to nonlinear dependence of the magnitude of res...
