Interplay Between the Lattice and Spin Degrees of Freedom in Magnetoelectric and Magnetic Materials
… and spin degrees of freedom in multiferroic and ferrimagnetic compounds by means of first-principles calculations and ab-initio-based Monte-Carlo simulations. We start with the reviews of magnetoelectricity, ferrimagnetism, strain engineering, followed by a brief introduction to first-principles …

Magnetic ordering and spin wave dynamics in transition metal arsenides
… in Mn3As2 from a paramagnet to a collinear ferrimagnet and then, into a canted spin state. Using high resolution synchrotron x-ray diffraction and neutron powder diffraction measurements, we identify magnetically coupled structural transitions in tetragonal CuMnAs which result from exchange …

Room temperature spin-orbit torque switching induced by a topological insulator
… switching is realized in topological insulator/ferrimagnet heterostructure at room temperature. Ferrimagnetic CoTb alloy with robust bulk perpendicular magnetic anisotropy is directly grown on a classical topological insulator Bi2 Se3. The low switching current density provides definitive proof …

Spin and Charge Transport in Metallic Ferrimagnets and Disordered Magnetic Oxides
… been exploring the use of thin film synthetic ferrimagnets and disordered magnetic oxides for applications in spintronic devices. Due to the antiferromagnetic exchange interaction, ferrimagnetic materials offer the ultrafast dynamics of the antiferromagnetic exchange, with a net magnetization …

A combined experimental and computational study of Ni<sub>3</sub>Pt/Ir/Co Synthetic Ferrimagnets: taking atomistic spin simulation into the laboratory
Synthetic ferrimagnets, two ferromagnetic layers exchange coupled antiferromagnetically through a non-magnetic spacer layer, provide an interesting test bed for future all optical magnetic switching and to validate, in an experimental and engineering context, the utility of atomistic spin modelling …

Cation Site Occupancy and Defect Engineering in Perovskite Heterostructures
… into a self-assembled nanocomposite with a ferrimagnet [formula] in order to demonstrate interfacial magnetic exchange coupling. We discuss how the growth condition affects cation site occupancy and crystal structure. Next, we describe a nontrivial self-assembly mechanism of [formula] and …

Synthesis and Characterization of Molecule-Based Magnets Containing Methyl-Substituted Phenyltricyanoethylene Acceptors
A new family of molecule-based magnets related to the V[PTCE]x · yCH2Cl2 magnet (PTCE = phenyltricyanoethylene, x = ~2, y = ~0.2) was synthesized utilizing new reversible one-electron acceptors with the general form MexPTCE (PTCE = phenyltricyanoethylene, x is the number of methyl groups on the …

TiO2 and ZnO metal oxides lattice defects driven magnetism and their contribution in discoloring of dyes
… existing in a ferromagnet and antiferromagnet/ferrimagnet interface is currently observed only in similar morphological nanostructures. This remarkable observation suggests an existence of mixed and itinerate magnetism in one material. We have found a consistent correlation between the …

Decoherence of Transverse Electronic Spin Current in Magnetic Metals
… on two specific materials: (1) CoGd alloys with ferrimagnetic sublattices, which resemble antiferromagnets near the compensation composition, and (2) elemental antiferromagnetic Cr, which can be grown as epitaxial films and hence serve as a model system material. For both the CoGd and Cr studies, …
