Three applications of ballistic electron microscopy are used to study, with nanometer-scale resolution, the magnetic and electronic properties of magnetic multilayer thin films and tunnel junctions. First, the capabilities of ballistic electron magnetic microscopy are demonstrated through an investigation of the switching behavior of continuous Ni80Fe20 /Cu/Co trilayer films in the presence of ...

In this study, we demonstrated the magnetoelectric control of magnetic thin films. (111)-textured Pd/Ni/ Pd thin films were prepared on mica/lead zirconium titanate (PZT) substrates for the investigation. The reversible modulation of magnetic coercivity in Ni films was observed through the electric-voltagecontrolled strain variation from the PZT substrate. For 14 nm Ni film, the applied electri...

This submitted manuscript describes the development, fabrication and characterization of soft-magnetic thin films for high frequency applications up to GHz frequencies. These high frequency suitable films were investigated with the prospective use as magnetic core material, for the assembly of micro inductors or micro sensors for the micro electronic and micro system technology. Within the scop...

Below its ordering temperature (TN = 90 K), bulk bcc Eu has a helical magnetic state with propagation vectors along the three equivalent 〈100〉 directions. In contrast, epitaxial (110)Eu films exhibit a unique magnetic ordering : the domain with a magnetic helix propagating along the in-plane [001] direction vanishes on cooling, at the expense of other domains with helices propagating along [100...

In this research, a thin film of TiO2 was applied on AZ91D using the method of magnetic sputtering. Microstructure investigations were done using field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD). Wear resistance for the coating was investigated using the pin on the disk in the form of dry and in the Ringer's solution. After this test, the worn surface of the sampl...

The residual stresses of the thin-walled injection molding are investigated in this study. It was realized that the behavior of residual stresses in injection molding parts was affected by different process conditions such as melt temperature, mold temperature, packing pressure and filling time. The layer removal method was used to measure the residual stresses at a thin-walled test sample by a...

Gupta, Department of Chemistry, Pittsburg State University, 1701 South Broadway, Pittsburg, KS-66762, USA e-mail: [email protected] Epitaxial tin ferrite (SnFe2O4) thin films were grown using KrF excimer (248 nm) pulsed laser deposition technique under different growth conditions. Highly epitaxial thin films were obtained at growth temperature of 650°C. The quality a...

The magnetic properties of a thin film consisting of an exchange-coupled [Co/Ni]2/NiFe multilayer has been studied as a function of the NiFe thickness by using Monte Carlo modeling and compared with experimental results of [Co/Ni]4/Co/NiFe multilayers. Both modeling and experiment showed that the NiFe thickness controls the effective anisotropy. The direction of the easy axis is determined by a...

Very thin CoCr films deposited on different underlayers on glass disk substrates were studied by the magneto-optic Kerr effect, VSM, torque magnetometcy and TEM selected area diffraction. Square or near square perpendicular loops were obtained from Co/Ti , CoCr/Au: CoCr/AI, CoCr/C and CoCr/Si films. TEM SAD study revealed that the crystalline structure is a key factor determining the magnetic a...
