Ferroelectric perovskite oxides possess a large electrocaloric (EC) effect, but usually at high temperatures near the ferroelectric/paraelectric phase transition temperature, which limits their potential application as next-generation solid-state cooling devices. We use classical molecular dynamics to study the electric-field-induced phase transiti...

The structural and magnetic properties of sputter-deposited epitaxial Pt t Pt/F e 7.5 Å (001) multilayers (t Pt= 0–15 Å) are investigated using x-ray diffraction, Kerr magnetometry, and x-ray magnetic circular dichroism (XMCD). X-ray diffraction shows that there is a crystalline phase change from bct to fct at a Pt thickness of≈ 4 Å. The Fe XMCD is...

It is demonstrated that x-ray magnetic linear dichroism (XMLD) in absorption spectroscopy is a viable technique for element-specific magnetic characterization of metallic thin films and multilayers. XMLD is measured at the Fe, Co, Cr, and VL 2, 3 edges, and varies from 1–11% of the edge jump in the absorption coefficient, with a magnitude that scal...

The structure and magnetic properties of Fe/Ru (001) multilayers are studied using x-ray diffraction, magneto-optical Kerr-effect magnetometry, and x-ray magnetic circular dichroism. The Fe layer thickness is maintained constant at 7.5 Å, while the nominal Ru layer thickness t Ru is variable. For t Ru
