Magnetic cell positioning is demonstrated by controlling the magnetic domain walls in ferromagnetic zigzag thin films. Magnetophoresis experiment is performed to determine the number of magnetic nanoparticles that enter the cells by endocytosis. It is observed that in the zigzag structure with larger wavelength the magnetic cells are better aligned at the vertices.

    The magnetization reversal process has been studied on a discontinuous metal-insulator multilayer sample [Co80Fe20(1.3 nm)/Al2O3(3 nm)]10 showing superferromagnetic (SFM) behavior. Size and shape of SFM domains can be changed by varying the angle θ between the magnetic field and the easy axis...

    We focus on a special type of domain wall appearing in the Landau-Lifshitz theory for soft ferromagnetic films. These domain walls are divergence-free $${\mathbb{S}^2}$$ -valued transition layers that connect two directions $${m_\theta^\pm \in \mathbb{S}^2}$$ (differing by an angle $${2\theta}$$...

    We experimentally demonstrate that the stress-induced magnetic anisotropy in composition-graded ferromagnetic NiFeTa layers can be employed to trigger exchange bias in NiFeTa/IrMn bilayers without using any deposition field or field cooling procedure. In particular, we found that the NiFeTa/IrMn...

    Devices based on mesas were fabricated from thin films of magnetically phase-separated La0.6Ca0.4MnO3. Low-field magnetoresistance arises because the volume fraction of the ferromagnetic metallic phase is large enough for percolation but small enough to permit magnetic decoupling between each...

    Ferromagnetic SrRuO3 films with controlled in-plane magnetic anisotropy have been deposited on nominally exact (miscut <0.1°) SrTiO3(001) substrates. Films grown on as-received substrates display in-plane uniaxial magnetic anisotropy whereas films grown on treated TiO2-terminated surfaces are...

    The fast domain wall dynamics of amorphous glass-coated microwires can be changed drastically by properly selected annealing temperature. Here, the effect of thermal annealing on the surface domain structure of microwires is examined. Imaging the surface domain structure by Bitter colloid...

    Domain wall propagation has been measured in continuous, weakly disordered, quasi-two-dimensional, Ising-like magnetic layers that are subject to spatially periodic domain wall pinning potentials. The potentials are generated non-destructively using the stray magnetic field of ordered arrays of...

    We study field-induced domain wall motion in permalloy nanowires with vertically etched nanotrench pinning site.

    Spintronics relies on the spin dependent transport properties of ferromagnets (Fs). Although antiferromagnets (AFs) are used for their magnetic properties only, some fundamental F-spintronics phenomena like spin transfer torque, domain wall motion, and tunnel anisotropic magnetoresistance also...
