Special Issue Information

Dear Colleagues,

Complex-oxide materials and their interfaces have garnered enormous interest in the last decade due to the potential for and realization of exotic phenomena in these systems, including emergent interfacial conduction, magnetic order, superconductivity, new ferroelectric order, etc. However, the field is still frequently discussed from various aspects. Such systems are promising for information technology devices, electrically controlled magnetic data storage, low power consumption, and magnetically operated electric devices. One of the most important open questions to address is in the understanding of the fundamental limits of the coupling and charge transfer at the interfaces, and how to expand it for applications. We are excited to offer a platform for some of this exciting new research with a Special Issue of the new open access journal, Magnetochemistry. This Special Issue aims to publish a collection of cutting-edge research articles which will present the latest achievements in the field of oxide interfaces, ferroelectric and multiferroic materials that will impact the development of the next generation of electronic devices.

Domain wall mobility as a function of nonmagnetic interlayer thickness and temperature was studied in ultrathin exchange-coupled ferromagnetic layers using magneto-optic Kerr microscopy. The system under study is a Pt/Co/Pt/Co/Pt heterostructure having perpendicular magnetic anisotropy and a middle Pt layer with spatially variable thickness. The ferromagnetic interaction between the Co layers is observed when the Pt interlayer thickness varies from 5 to 6 nm in a temperature range of 200–300 K. There is a certain interval of Pt layer thickness where domain walls in both ferromagnetic layers move independently. Nonlinear dependence of the domain wall displacement on the applied field was measured. It is shown that an equilibrium position of the relaxed domain wall depends on field, temperature, and the nonmagnetic interlayer thickness. This position is determined by the energy balance: (i) domain wall displacement provided by the applied field, (ii) interlayer exchange interaction in the area swept by the domain wall, and (iii) domain wall coercivity. The mechanism of domain wall stabilization in terms of independent wall motion near critical thickness was considered. It is found that both the coercivity of the Co layer and the critical thickness decrease at higher temperature, while the interlayer exchange constant J is changed weakly. Full article
