We discuss the application of polarised neutron reflection to layer selective vector magnetometry measurements in thin magnetic films. To illustrate the application of PNR, we review recent measurements of the absolute moment in X/Fe/Ag(001) structur

A technique for engineering micron and submicron scale structures from magnetic films of transition metals has been developed using a combination of electron- and ion-beam lithography enabling high-quality arrays of submicron magnetic Fe wires to be

We have combined polarised neutron reflection (PNR), X-ray reflection, the extraordinary Hall effect (EHE) and magnetoresistance (MR) in a detailed multi-technique study of the magnetic properties of a 200 A polycrystalline Co film supported by a GaA

LaBella et al . ([1][1]) claimed 92% spin polarization for electrons injected into gallium arsenide [GaAs(110)] from a Ni scanning tunneling microscope (STM) tip, which, they asserted, emitted 100% spin-polarized electrons. Such a claim, if substanti

We studied layer selectively the magnetic moments on a Cu/9 Å Co/50 Å Ni/Cu/Si(001) and a Cu/50 Å Ni/Cu/Si(001) structure using polarized neutron reflection. The magnetic moments for the Cu/Co/Ni/Cu structure are 1.70±0.20 μB and 0.57±0.05μB f

Polar magneto-optic Kerr effect (MOKE) measurements on an epitaxial Cu/Co (23 angstroms)/Cu (0-49 angstroms)/Ni (53 angstroms)/Cu/Si(001) structure reveal that the Ni magnetization is aligned in plane for zero Cu spacer layer thickness and becomes in

We report on experimental coercive field measurements for ultrathin films of Co on Cu{1 1 0}, revealing a complex dependence upon the surface coverage of oxygen and hydrogen adatoms. With reference to first-principles calculations, we rationalise thi
