R-VSM and MOKE magnetometers for nanostructures

The influence of NiFe thickness of top-electrode on exchange coupling parameters of IrMn based MTJ

“…These are optimum annealing conditions to obtain maximum of MR ratio [3]. The magnetic measurements were performed by R-VSM and MOKE described elsewhere [4]. In order to find the correlation between structure and magnetic properties the samples have been characterized by XRD experiment (with Cuanode) in GID (scan-2y) and y22y geometry and by rocking curve (scan-o).…”

Distribution of switching fields in thin films with uniaxial magnetic anisotropy

“…The first was magneto-optical Kerr effect (MOKE) in longitudinal geometry. In addition to the normal set-up [20], a modulator was used as a polarisation analyser, which provides high sensitivity to Kerr rotation ( $ 1 m) and is not sensitive to ellipticity.…”

“…In addition to the normal set-up [20], the VSM designed in IMRE has a two-axis capability. The acceptance coil can be placed in two positions to measure the component of magnetisation in the sample either parallel or perpendicular to the applied field.…”

Influence of fluxing in the preparation of bulk Fe-based glassy alloys

“…Magnetic properties were measured at room temperature on ribbon specimens with 1.5 mm × 1.5 mm dimensions using a Vibrating Sample Magnetometer (VSM) described elsewhere [10]. The ribbon is attached to the end of a glass pipe-rod, which oscillates with mechanical resonance frequency of the rod-sample system (75 Hz).…”
