A method to characterize the magnetic moment of a magnetic force microscopy (MFM) tip is presented. The response of the MFM while imaging a superparamagnetic film is compared to a nonmagnetic reference. A simple model is used to compare the experimen

Highly ordered, single-crystal Fe4N films were prepared on single-crystal SrTiO3 (001) substrates by reactive magnetically enhanced dc triode sputtering. Analytical techniques, including x-ray diffraction, reflectivity, ion channeling, and atomic for

The magnetic behavior of exchange biased Co/CoO polycrystalline thin films has been investigated using magnetometry and magneto-optical (MO) imaging. For CoO layer thicknesses of about 30 A, these films exhibit a strong training effect below the bloc

The magnetic reversal of bcc Fe1−xCox thin films on vicinal Sc1−yEryAs/GaAs(100) is modified by changing the relative strength of the uniaxial and cubic magnetocrystalline anisotropies using substrates with different miscut angles. The surface mi

A unidirectional magnetotransport anisotropy observed in thin films of exchange-biased ferromagnetic manganites is used to measure temperature dependence of exchange bias in these structures. Values of both the exchange field and the blocking tempera

We have measured the magnetic domain patterns in Co/Pd multilayers of varying thickness using magnetic force microscopy in the presence of an external magnetic field applied perpendicular to the multilayers. We find that the domain patterns evolution

We recently demonstrated that alloy composition can be used to fine tune the position of the Fermi level in ${\mathrm{Co}}_{1\ensuremath{-}x}{\mathrm{Fe}}_{x}{\mathrm{S}}_{2}$ alloys leading to composition-controlled spin polarization and the ability

In the emerging field of spin-electronics ideal ferromagnetic electron sources would not only possess a high degree of spin polarization, but would also offer control over the magnitude of this polarization. We demonstrate here that a simple scheme c

Summary form only given. A microscopic understanding of the ferromagnetic/antiferromagnetic (F/AF) direct exchange coupling remains elusive. An experimental technique, based on the anisotropic magnetoresistance (AMR), to determine both the magnitude
