Special Issue Information

Dear Colleagues,

In recent years, the incorporation of magnetic spins into organic–inorganic hybrid materials with electronic, magnetic and optical properties has aroused a great deal of attention for abundant fundamental physics and multifunctional applications, such as magneto-electric coupling and magneto-optical effect. The underlying magnetism in organic magnetic systems such as molecular magnets, organometallic frameworks, organic–inorganic hybrid magnets and confined low-dimensional magnetic systems of 0D, 1D and 2D nanostructures has been widely studied both theoretically and experimentally. However, there are major challenges for the development of organic magnets with strong magnetic properties (e.g., ferromagnetism or ferrimagnetism) and their magnetic ordering temperatures at or near room temperature. Organic magnetic materials offer the possibility of tuning magnetic properties through synthesis, which is different from conventional metal/alloy/oxide magnets. The study of strategies for the design and synthesis of room-temperature magnetic multifunctional hybrid materials/devices offers great opportunities to both chemists and physicists. These efforts have led to the novel fabrication of low-dimensional magnetic systems as initial building blocks for magnetic hybrid materials and nanocomposite magnets. The study of the interplay between nanostructures/construction modes and physics in these hybrid systems paved the way for the fabrication of multifunctional magnetic/electric/spintronic devices. The aim of this Special Issue is to attract world-leading scientists to present the latest exciting theoretical and experimental results in the field of magnetic hybrid materials/nanostructures/nanocomposites, discussing the underlying physics in different magnetic nanomaterials/systems and unveiling their multifunctional applications. This Special Issue calls for theoretical studies, experimental observations, measurements and development works, as well as potential applications.

The YFeO3 orthoferrite is one of the most promising materials for antiferromagnetic (AFM) spintronics. Most studies have dealt with bulk samples, while the thin YFeO3 films possess unusual and variable properties. Ultrathin (3–50 nm) YFeO3 films have been prepared by magnetron sputtering on the r-plane (1 1¯ 0 2)-oriented Al2O3 substrates (r-Al2O3). Their characterization was undertaken by the Mössbauer reflectivity method using a Synchrotron Mössbauer Source and by X-ray diffraction (XRD) including grazing incidence diffraction (GI-XRD). For thin films with different thicknesses, the spin reorientation was detected under the application of the magnetic field of up to 3.5 T. Structural investigations revealed a predominant orthorhombic highly textured YFeO3 phase with (00l) orientation for relatively thick (>10 nm) films. Some inclusions of the Y3Fe5O12 garnet (YIG) phase as well as a small amount of the hexagonal YFeO3 phase were detected in the Mössbauer reflectivity spectra and by XRD. Full article
