Superconducting Pb( x )/Au(25 nm) bilayers ( x = 50, 100 nm) patterned with antidot lattices exhibit various matching field anomalies depending on experimental conditions. Magnetization peaks at applied fields H = n [20 Oe] ( n = integer) resemble su

Low-temperature magnetic force microscopy (LT-MFM) was used to study the distribution of superconducting vortices in Nb above a square array of 1 μm-sized circular ferromagnetic dots in a magnetic-vortex state. The force that the MFM tip exerts on t

By using micro-magnetic simulations we demonstrate how the shape of magnetic nano-elements affects the out-of-plane component of the magnetization in magnetic dots and rings. We show that by removing the highly energetic out-of-plane magnetic vortex

It was suggested that the shape effects are responsible for the vortex formation and chirality in circular ring elements. We found that the introduction of well-controlled asymmetry into permalloy rings provides precise control of the switching mecha

Recent studies on Co and permalloy rings have shown that a totally flux-closed magnetic vortex state could be stable at remanence. The two chiralities of the vortex, clockwise and counterclockwise, have been proposed as the carriers for the stored in

Recent studies on cobalt and permalloy rings have shown that a totally flux-closed magnetic vortex structure is stable at remanence. The two chiralities of the vortex, clockwise and anti-clockwise, have been proposed as the carriers for the stored in

AC magnetization measurements are reported for a superconducting Pb (500 A)/Cu (100 A) film bilayer with a triangular lattice of antidots of diameter D =0.35 μm and spacing d =1.0 μm. Sharply peaked magnetization anomalies occur at applied DC magne

We study the influence of artificial pinning centers on the vortex critical velocity in Al thin films deposited on top of a periodic array of Permalloy (FeNi) square rings. We demonstrate that the field dependence of the flux flow velocity strongly d

The transport properties of an Al type-II superconducting thin film covering a Py plain film with a rectangular array of triangular holes are investigated. We show that, although the magnetization of the Py lies in the plane of the structure, both th

In this work we present experimental results on the rectification of vortices in a superconductor/ferromagnet system under a high frequency drive. The two-dimensional pinning landscape, induced by the stray fields of the ferromagnetic template, has n
