The Synchrotron-based X-Ray Absorption Near-edge Spectroscopy (XANES) and Polarized Neutron Reflectivity (PNR) techniques were employed to investigate the structural properties of BiFe$_{1-x}$Mn$_{x}$O$_{3}$ ceramic and Co/CoO/Au multilayer, especially to study the local structure of Mn in BiFe$_{1-x}$Mn$_{x}$O$_{3}$ ceramic and to verify the formation of secondary phase in Co/CoO/Au...
RF-sputtered Co71Pd29 film with the thickness of 117 nm was deposited on glass and on Al, Co, Cr and Ni under-layers. Magnetic and electrical properties were measured by VSM and 4-point probe techniques. All prepared Co-Pd film showed ferromagnetic phase at room temperature. The Magnetic anisotropy of all films excluding on Ni under-layer tended to normal to film plane. The parallel magnetic...
In this paper, magnetic force microscopy (MFM) probes with different coating materials were characterized under AC magnetic field. A perpendicular magnetic write head similar to those used in hard disk drives was employed as the AC magnetic field generator. In order to measure a response of MFM probes to AC magnetic field, a MFM probe under test was scanned, at a scan height of 10 nm, across...
Magnetic force microscopy (MFM) was employed to characterize the magnetic field distribution of two different designs of perpendicular magnetic writers with fully wrap-around shield (WAS). Typical magnetic write heads, located on a slider at the so-called air bearing surface (ABS), are composed of a magnetic write pole and a magnetic return pole. The write pole has a much small cross section...
In this work, Zn$_1$$_-$$_x$Fe$_x$O (x=0.000, 0.0625 and 0.125) materials have been investigated in both experimental and theoretical aspects. The pure and Fe-doped ZnO nanoparticles were prepared by a combustion method. The crystal structures were characterized using the X-ray diffraction (XRD), morphology by the transmission electron microscopy (TEM) techniques, magnetic behavior by...
