Micromagnetic ripple structures on the surfaces of thick specimens of ultra-soft magnetic material having strong surface anisotropy Ks favouring out-of-surface magnetization have been calculated. These ripples have wavelengths of the order of 0.1 μm and extend to a depth ∼ √A/Ms, where A is the exchange constant and Ms is the saturation magnetization. The wave-vectors of the ripple structures are either transverse or parallel to the bulk magnetization. Both structures have lower energy than the one-dimensional structure discussed by O'Handley and Woods, and they exhibit stronger normal magnetization. The transverse structure requires a surface anisotropy Ks ≥ 0.80K0, where is that required for the one-dimensional structure. The threshold for longitudinal ripples is 0.84K0. It is suggested that the transverse structure probably constitutes the ground state. The magnitudes of Ks and A should be obtainable from measurements of the ripple wavelength and amplitude, and Ms.

Background: Interprofessional education (IPE) introduced at the beginning of pre-registration training for healthcare professionals attempts to prevent the formation of negative interprofessional attitudes which may hamper future interprofessional collaboration. However, the potential for IPE depends, to some extent, on the readiness of healthcare students to learn together. Objectives: To measure changes in readiness for interprofessional learning, professional identification, and amount of contact between students of different professional groups; and to examine the influence of professional group, student characteristics and an IPE course on these scores over time. Design: Annual longitudinal panel questionnaire survey at four time-points of pre-registration students (n = 1683) drawn from eight healthcare groups from three higher education institutions (HEIs) in the UK. Results: The strength of professional identity in all professional groups was high on entry to university but it declined significantly over time for some disciplines. Similarly students’ readiness for interprofessional learning was high at entry but declined significantly over time for all groups, with the exception of nursing students. A small but significant positive relationship between professional identity and readiness for interprofessional learning was maintained over time. There was very minimal contact between students from different disciplines during their professional education programme. Students who reported gaining the least from an IPE course suffered the most dramatic drop in their readiness for interprofessional learning in the following and subsequent years; however, these students also had the lowest expectations of an IPE course on entry to their programme of study. Conclusion: The findings provide support for introducing IPE at the start of the healthcare students’ professional education to capitalise on students’ readiness for interprofessional learning and professional identities, which appear to be well formed from the start. However, this study suggests that students who enter with negative attitudes towards interprofessional learning may gain the least from IPE courses and that an unrewarding experience of such courses may further reinforce their negative attitudes.
