Abstract

We constructed supercells for modeling diamond‐like carbon (DLC) structures and doped them with Cr atoms in order to investigate the presence of magnetism, which was recently observed experimentally. The total energies for the magnetic and non‐magnetic (NM) states were calculated ab initio within the framework of the density‐functional theory (DFT). We found that an external strain is required for the ferromagnetic state to be energetically the most favorable.

The electronic structures and magnetic properties in Carbon-doped CeO 2 have been investigated by means of first-principles calculations based on the LSDA+U scheme. The results demonstrate a magnetic moment of 2.00 µ B per supercell with one Carbon dopant which mainly stems from Hund's rule coupling

## Abstract The non‐destructive characterization of intrinsic stress is very important to evaluate the reliability of devices based on diamond‐like carbon (DLC) films. Whereas the only requirement for the X‐ray diffraction method is a crystalline state of specimen, Raman spectroscopic stress analys
