RESUMO
An ultra-high vacuum compatible multipurpose chamber for magneto-optical reflection and transmission experiments with polarization analysis on magnetic systems is introduced. It is applicable in a broad photon energy range from the visible to the soft x-ray regime and for a wide angular range from grazing to normal incidence. It exploits a novel magnetization device based on rotating permanent magnets, which generates tuneable magnetic fields up to 570 mT in longitudinal, transverse and polar geometry. The unique combination of these features enables the feasibility of all typical magneto-optical spectroscopy techniques as T-MOKE, L-MOKE, P-MOKE, x-ray magneto optical linear dichroism, x-ray magnetic circular dichroism in reflection and Kerr polarization-spectroscopy, which is demonstrated for Co with focus on the Co 3p edges.
RESUMO
Strategies used by latency-aged children to cope with pediatric migraine pain are identified in this exploratory study. The following three broad categories of coping and their subtypes emerged from the data: affective, cognitive, and problem-focused coping. Implications for practice, research, and education, particularly regarding the use of spirituality and prevention, are discussed.
