The recently proposed concept of a Hund's metal - a metal in which electron correlations are driven by Hund's rule coupling - can be used to explain the exotic magnetic and electronic behaviour of strongly correlated electron systems of multi-orbital

We demonstrate using inelastic scanning tunneling spectroscopy (ISTS) and simulations based on density functional theory that the amplitude and sign of the magnetic anisotropy energy for a single Fe atom adsorbed onto the Pt(111) surface can be manip

Atomic Spin-Transfer Torque Efficient electrical control of magnetism is a major goal of spin-based electronics. In many setups, spin-polarized current is used to switch the magnetization of a magnetic layer. This phenomenon, known as the spin-transf

The robustness of the gapless topological surface state hosted by a 3D topological insulator against perturbations of magnetic origin has been the focus of recent investigations. We present a comprehensive study of the magnetic properties of Fe impur

A combined experimental and theoretical study of doping individual Fe atoms into Bi2Se3 is presented. It is shown through a scanning tunneling microscopy study that single Fe atoms initially located at hollow sites on top of the surface (adatoms) can
