Nanomagnets with high shape anisotropy and strong crystalline anisotropy: perspectives on magnetic force microscopy.

We report on a new approach for magnetic imaging, highly sensitive even in the presence of external, strong magnetic fields. Based on FIB-assisted fabricated high-aspect-ratio rare-earth nanomagnets, we produce groundbreaking magnetic force tips with hard magnetic character where we combine a high aspect ratio (shape anisotropy) together with strong crystalline anisotropy (rare-earth-based alloys). Rare-earth hard nanomagnets are then FIB-integrated to silicon microcantilevers as highly sharpened tips for high-field magnetic imaging applications. Force resolution and domain reversing and recovery capabilities are at least one order of magnitude better than for conventional magnetic tips. This work opens new, pioneering research fields on the surface magnetization process of nanostructures based either on relatively hard magnetic materials-used in magnetic storage media-or on materials like superparamagnetic particles, ferro/antiferromagnetic structures or paramagnetic materials.

Factors affecting Department of Defense patient satisfaction in a military emergency department.

This descriptive, correlational study was conducted to explore factors (nurses and staff, doctors, waiting and convenience issues, and tests and treatments) and specific interpersonal behaviors affecting Department of Defense patient satisfaction in a military emergency department (ED). Data from a random sample of 534 patients using a mail-back questionnaire (N = 178) revealed that military patients who perceived the staff to have treated them courteously, taken their problems seriously, and paid attention to them during their stay were more satisfied with their military ED encounter. Patient satisfaction, expressed as likelihood to recommend the facility, was independent of major demographic characteristics such as age and sex. Our findings suggest that a patient's perception of the ED encounter, particularly the interactions between the patient and staff, ultimately influence satisfaction. Significant improvements in patient satisfaction might be realized if quality improvement efforts focus on providing ED staff specific training in interpersonal interactions.
