Criteria for Defining Authorship: Equally Important for Textbooks and Educational Resources

Strict criteria to determine entitlement to authorship of manuscripts submitted to peer reviewed journals is a hallmark of quality. To date this expectation has not been applied to the authorship of textbooks and other educational resources. This paper discusses criteria for authorship and applicability to the textbook and educational resource market. Failure to apply criteria in this domain could weaken the academic status of these contributions to learning and teaching for the health professions, particularly nursing

Effect of Vanadium on the RE and Fe Sublattice Anisotropies in some REFe12-xVx (RE= Y, Er, Tb) Tetragonal Compounds

The compounds REFe12−xVx(RE=Y,Er,Tb) having the tetragonal crystal structure of ThMn12 exist in the composition range 1.5≤x≤4. The dependence of the magnetic properties on the vanadium content were investigated in order to evidence and study any influence of vanadium on the magnetic anisotropy of both iron and RE sublattices and, as a consequence, on the magnetic phase diagram of these systems. The influence of vanadium was found to be remarkable on Tc, Ms, and Fe anisotropy, which decrease in all the compounds with increasing V content. However the largest effect was observed on the RE anisotropy and particularly in TbFeV, where the anisotropy of the Tb sublattice is turned from planar to axial by increasing the vanadium concentration, thus giving rise to strong effects on the macroscopic magnetic behavior and on the magnetic phase diagram of these systems. The large variation of the spin reorientation transition temperature Tsr, observed by varying V content on both ErFeV and TbFeV, can justify the spread in the literature data which could be attributed to small not considered stoichiometry differences with respect to the nominal composition
