This review article first presents a summary of current understanding of the magnetic
properties and intrinsic ferromagnetism of transition-metal (TM)-doped ZnO films, which are …

Reports of room-temperature ferromagnetism continue to emerge for an ever-growing range
of nanomaterials with a small or even vanishing concentration of magnetic atoms. Dilute …

The well-known “band-gap” problem in approximate density functionals is manifested mainly
in an overly low energy of the conduction band (CB). As a consequence, the localized gap …

Composite multiferroics containing ferroelectric and ferromagnetic components often have
much larger magnetoelectric coupling compared to their single-phase counterparts. Doped …

An overview of X-ray magnetic circular dichroism (XMCD) spectroscopy in the hard X-ray
range is presented. A short historical overview shows how this technique has evolved from …

The use of synchrotron-based spectroscopy has revolutionized the way we look at matter. X-
ray absorption spectroscopy (XAS) using linear and circular polarized light offers a powerful …

In this work, we study the interface obtained by depositing a monolayer of a Blatter radical
derivative on polycrystalline cobalt. By examining the occupied and unoccupied states at the …

First-principles calculations are performed to study the magnetism mechanism in undoped
ZnO and ZnO doped with nonmagnetic elements X (X= Li, Mg, and Al). In undoped ZnO, it is …

Using first-principles calculations it is demonstrated that Co doped graphenelike ZnO sheet
presents ferromagnetic coupling. The Co atoms are energetically barrierless absorbed in the …

Owing to the variety of possible charge and spin states and to the different ways of coupling
to the environment, paramagnetic centres in wide band-gap semiconductors and insulators …
