Unusually large magnetic anisotropy in electrochemically deposited Co-rich Co-Pt films.

Co-rich Co-Pt films grown by electrodeposition from an amino-nitrite/citrate/glycine electrolyte onto Au(111) substrates apparently grow with a hexagonal structure, with its c-axis directed perpendicular to the surface. The films exhibit a perpendicular magnetic anisotropy (MCA) of the same order of magnitude as the shape anisotropy. Experimental estimates of the MCA result in a higher anisotropy than that reported for bulk materials of the same composition, but similar to values measured in films grown by vacuum methods at relatively high temperature, which partly consist of a high anisotropy, metastable orthorhombic Pmm2 phase. Comparison of valence band X-ray photoelectron spectroscopy measurements on electrodeposited films with density functional theory simulations of the electronic structure of the various reported Co(3)Pt structures support the notion that the films may consist of a mixture of the hexagonal and the Pmm2 structure.

Assessment of dysfunctional working models of self and others in schizophrenic patients: a summary of data collected in nine nations. International Research Group.

OBJECTIVE: To investigate the cross-cultural feasibility of a new scale for assessing dysfunctional working models of self and others, and to evaluate its discriminative power. METHOD: Schizophrenic patients (N=351), non-psychotic patients (N= 86) and non-clinical subjects (N= 511) collected in 10 centres completed the DWM-S. Current psychopathology was assessed by means of the BPRS. RESULTS: Alpha coefficients were high in all samples. Mean scores on the DWM-S appeared to be comparable in all countries, suggesting cross-national generalizability. No significant correlation was found with sex, age, levels of psychopathology and duration of illness. Discriminant analyses showed that more than 70% of the schizophrenic patients are correctly classified. CONCLUSION: The DWM-S is an easily administered self-report instrument which allows to pinpoint internal dysfunctional working models of self and others in various types of patients. It is a useful tool for case conceptualization, especially when psychotherapeutic interventions are part of the treatment programme.
