The influence of 30 keV Ga + ion irradiation on the magnetic properties of polycrystalline NiFe/FeMn exchange bias layers was investigated. In this context, it was of particular interest to determine whether a previously observed enhancement of the b

All-optical control of the magnetization of polycrystalline exchange bias bilayer systems is achieved using short picosecond laser pulses. Due to the photoexcitation, the spin temperature across the interface between the ferromagnetic and antiferroma

We demonstrate that antiferromagnetically coupled Fe/Cr/Fe trilayers can be magnetically patterned on the micrometer and sub-micrometer scale by irradiation with keV Ga + ions, which induces a local transition to ferromagnetic coupling due to direct

The influence of the ion irradiation by 30 keV Ga{sup +} ions on the crystal structure, chemical ordering, magnetic properties, and topography of epitaxial Fe/Cr/Fe trilayers was investigated by different analytical techniques. We present direct expe

We investigate the formation of magnetic domains in a magnetic trilayer patterned using ion beam bombardment. The system consists of a finite array of in-plane magnetized ferromagnetic Fe elements embedded into an antiferromagnetically coupled Fe∕C

A unique type of ferromagnetic microelement is explored. Unlike conventional ferromagnetic elements, the entities studied here are not separated topographically from each other, but embedded into a surrounding, continuous film. Fabrication of such el

Magnetic anisotropies and magnetization reversal properties of the epitaxial Heusler compound Co$_2$Cr$_{0.6}$Fe$_{0.4}$Al (CCFA) deposited on Fe and Cr buffer layers are studied. Both samples exhibit a growth-induced fourfold anisotropy, and magneti

Co$_2$FeSi(100) films with L2$_1$ structure deposited onto MgO(100) were studied exploiting both longitudinal (LMOKE) and quadratic (QMOKE) magneto-optical Kerr effect. The films exhibit a huge QMOKE signal with a maximum contribution of up to 30 mde
