Magnetic stray fields of Co-Cr microstrips are investigated for bit stabilization in a vertical Bloch line memory (VBLM). The stray fields were revealed using Lorentz force based Foucault and differential phase contrast (DPC) techniques in a transmission electron microscope. The assumed shape of the stray fields for VBLM use has been experimentally verified. Agreement between experiment and sim...
v-shaped and triangular cantilevers are widely employed in atomic force microscope (afm) imaging techniques due to their stability. for the design of vibration control systems of afm cantilevers which utilize patched piezo actuators, obtaining an accurate system model is indispensable prior to acquiring the information related to natural modes. a general differential quadrature element method (...
Quantized magnetic disks consisting of an array of single domain Ni pillars with a density of 18 Gbits/in. were fabricated using nanoimprint lithography ~NIL! and electroplating. The total disk area, limited by the NIL mold, is 4 cm34 cm, leading to a total 45 Gbits. Magnetic force microscope ~MFM! images show that all pillars 70 nm in diameter and 400 nm in height are single domain. The magnet...
The first electron microscope was designed in 1931 by Ernest Ruska, as his diploma thesis at the Faculty of Engineering in Berlin; it was designed on the bases of Busch’s theory about electronic lens. (Fg.1). The microscope had magnification of only 17 times. In his doctoral dissertation in 1933 Ernest Ruska developed a new electron microscope with three electromagnetic lenses. The magnificatio...
Calculations of the interaction between a magnetic tip of an atomic force microscope with a magnetic surface using the non-collinear extension of the Alexander-Anderson model are described. The mechanism and rate of thermally activated magnetic transitions in a cluster of atoms at the tip is investigated. The results are compared with experimental data and found to be in good agreement with mea...
