Magnetism of Cr surface defects

Magnetic moment distribution in Cr(0 0 1) and Cr(1 1 0) films with strips and random defects at surface are calculated in the framework of a periodic Anderson model. All Cr(0 0 1) films reveal an appreciable surface magnetic moment the value of which depends on the type of defect. The film with flat...

Summary:Magnetic moment distribution in Cr(0 0 1) and Cr(1 1 0) films with strips and random defects at surface are calculated in the framework of a periodic Anderson model. All Cr(0 0 1) films reveal an appreciable surface magnetic moment the value of which depends on the type of defect. The film with flat Cr(1 1 0) surface does not exhibit any magnetization because of an equal number of atoms with opposite moments. Only well-ordered defects like one atom strips can give a noticeable magnetization in Cr(1 1 0) films.
