Presently, the best epitaxial thin films of CrO2 are made by chemical-vapor deposition (CVD) in a two-zone furnace with oxygen flow from a CrO3 precursor. The growth mode has previously been described as CrO3 vaporizing in the first zone, and thermal

Magnetite (Fe3O4) films and multilayers were grown using plasma-assisted molecular beam epitaxy and result in single-phase films grown in registry with a MgO substrate. No evidence of interdiffusion is detected on as-grown films. Both structural and

We have investigated the structural and compositional changes that are induced by the segregation of substrate Mg to the surface of $1\ensuremath{\mu}$m-thick ${\mathrm{Fe}}_{3}$O${}_{4}(001)$ films on MgO(001). The thin films have been grown with pl

Superlattices of Fe3O4–NiO layers have been studied by high-resolution transmission electron microscopy (HRTEM). These superlattices are grown by oxygen-plasma-assisted molecular-beam epitaxy (MBE) on (001) oriented MgO substrates, and exhibit a hi

The magnetic properties of [1 0 0] oriented Fe3O4/NiO and Fe3O4/CoO multilayers, MBE-grown on MgO(0 0 1) substrates, have been studied by polarized neutron reflectometry. In both samples, the Fe3O4 layer exhibits a depth-dependent magnetic profile ch

Using neutron diffraction, x-ray scattering, and bulk-magnetization methods, we have characterized the magnetic structure for ${\mathrm{Fe}}_{3}$${\mathrm{O}}_{4}$/NiO superlattices grown by molecular-beam epitaxy. The antiferromagnetic NiO order ext

Presented are studies of the magnetic and structural ordering in superlattices composed of Fe3O4 and NiO, and their study by a variety of techniques including x‐ray and neutron diffraction, and SQUID magnetometry. X‐ray diffraction indicates that

We have magnetically characterized single crystal Fe3O4/NiO superlattices grown on MgO(001), where the layer thickness has been varied over a wide range. Hysteresis for modulation wavelength Λmod = 258 A is similar to bulk Fe3O4, while loops for Λm

We have utilized molecular-beam-epitaxy techniques in an electron-cyclotron-resonance oxygen plasma to synthesize thin films of NiO, ${\mathrm{Fe}}_{3}$${\mathrm{O}}_{4}$ (magnetite), and modulated structures of these compounds with repeat structures

Oriented single-crystalline thin films of NiO and ${\mathrm{Fe}}_{3}$${\mathrm{O}}_{4}$, and ${\mathrm{Fe}}_{3}$${\mathrm{O}}_{4}$/NiO superlattices have been grown on cleaved and polished substrates of MgO(001), using oxygen-plasma-assisted molecula
