MnSi1.7_{1.7} nanoparticles embedded in Si: Superparamagnetism with a collective behavior

The doping of Mn in Si is attracting research attentions due to the possibility to fabricate Si-based diluted magnetic semiconductors. However, the low solubility of Mn in Si favors the precipitation of Mn ions even at non-equilibrium growth conditions. MnSi$_{1.7}$ nanoparticles are the common precipitates, which show exotic magnetic properties in comparison with the MnSi$_{1.7}$ bulk phase. In this paper we present the static and dynamic magnetic properties of MnSi$_{1.7}$ nanoparticles. Using the Preisach model, we derive the magnetic parameters, such as the magnetization of individual particles, the distribution of coercive fields and the inter-particle interaction field. Time-dependent magnetization measurements reveal a spin-glass behavior of the system.Comment: 11 pages, 6 figures, submitted to PR

Sustainability Pedagogies for the Business Language Classroom

Heightened urgency about the question of the earth’s survival has generated increased attention to how to teach sustainability across the curriculum. The business language course, positioned at the nexus of business and the humanities, is the ideal environment for bringing to bear perspectives from multiple disciplines on questions around sustainability. This article examines the notion of “sustainability pedagogies” framed within three key aspects of sustainability education noted in the scholarship: interdisciplinarity, transformative learning, and experiential learning. In each of these areas, we provide an example of how the sustainability pedagogies can be implemented in business language courses
