During the 1990s, Roger Cowley had a strong interest in the crystal and magnetic structures of rare-earth superlattices as a means to understand the rich and exotic magnetic properties of the rare-earth metals. High-quality samples can be grown by mo

A large-scale striped array with 7.5 µm width has been fabricated in an epitaxial (110) single crystal [20 A DyFe 2 /80 A YFe 2 ] 40 superlattice using a UV direct writing system. The [−112] direction perpendicular to the [1−11] easy axis of the

Fe/Mn is a model system in which to study exchange bias, since the antiferromagnetic (AF) Mn layers are believed to have uncompensated moments with all spins aligned in the plane and parallel to those of the Fe. We have determined the microscopic AF

A range of properties is surveyed for three barium lanthanum fluoride compounds, where the lanthanum ion may be holmium, erbium or thulium. The experimental methods include magnetic resonance, and optical absorption spectroscopy, together with measur

The properties of Ho/Sc superlattices grown by molecular beam epitaxy (MBE) have been investigated using X-ray and neutron diffraction techniques. Structural studies reveal the novel existence of more than one a lattice parameter. Examining the magne

SQUID magnetometry and polarised neutron reflectivity measurements have been employed to characterise the magnetic properties of U/Fe, U/Co and U/Gd multilayers. The field dependence of the magnetisation was measured at 10K in magnetic fields from -7

Spin-polarised neutron reflectometry has been used to investigate a magnetic exchange spring, formed in a (75Å DyFe2/150Å YFe2) × 18 multilayer thin film. The existence of an exchange spring is found to enhance the level of neutron spin flipping d

Anisotropic and giant magneto-resistance (AMR and GMR) measurements for a molecular beam epitaxy grown (1 1 0) multilayer film [50 A-DyFe 2 /50 A-YFe 2 ]×40 at 100 K are reported. The film possesses a bending field B B ∼5 T and an irreversible swi

We present the results of a study of the chemical and magnetic structures of Ho/Y and Ho/Lu superlattices, all grown by molecular beam epitaxy. By combining the results of high-resolution X-ray diffraction with detailed modelling we show that the sup
