The microscopic origin of training in exchange coupled systems has been identified from our experimentally observed microscopic suppression of training. It is an interplay of uniaxial anisotropy and uncompensated spins in the antiferromagnet grains that are rotatable in polycrystalline antiferromagnetic layer similar to spin-glass-like behavior.

    An alternative mechanism for exchange bias for ferromagnet/antiferromagnet bilayers with completely compensated interfaces is proposed and analyzed within the biquadratic coupling model. We show that a distribution of anisotropies in the antiferromagnet can lead to the appearance of exchange...

    The exchange bias effect is known to depend strongly on the condition of the ferromagnet/antiferromagnet interface. Bilayers of single-crystal Fe and polycrystalline KNiF[sub 3] were grown and exchange bias observed using superconducting quantum interference device magnetometry. Hysteresis loops...

    We have studied and analyzed the laser-induced voltage effect in highly c-axis-oriented polycrystalline NaxCoO2. The textured and layered stacking NaxCoO2 (x ∼ 0.7) bulks were prepared by a solid-state reaction process. Under the irradiation on Na0.67CoO2 bulk surface with pulsed laser...

    We have synthesized polycrystalline RRhSn (R = Tb-Tm) compounds, which crystallize in the hexagonal structure with space group [formula]. All the compounds, except HoRhSn, are antiferromagnetic at low temperatures. TbRhSn and DyRhSn show multiple magnetic transitions and metamagnetic behavior....

    Magnetic measurements of La2NiMnO6 reveal that its inverse susceptibility exhibits an upward derivation from Curie–Weiss behavior above TC, indicating the presence of a short-range ferromagnetic ordered state. It is suggested that the upward derivation is due to antiferromagnetic...

    An experimental study on the exchange bias properties of bulk polycrystalline Ni50Mn50-xSnx Heusler alloys has been performed. Martensitic transformations have been observed in the alloys for some critical Sn concentrations. The alloys, while in their respective martensitic phases, are found to...

    We report on room temperature ferromagnetic resonance (FMR) studies of [ t Co|2t Ni] � N sputtered films, where 0.1 = t = 0.6 nm. Two series of films were investigated: films with the same number of Co|Ni bilayer repeats (N = 12), and samples in which the overall magnetic layer thickness...

    We have performed a critical experimental evaluation of the dependence of both perpendicular magnetic anisotropy and exchange bias on the structure of the ferromagnet (FM)/nonferromagnet and FM/antiferromagnet interfaces of (Co/Pt)n and (Co/Pt)n/FeMn multilayers. The growth of these...
