This engineering/materials study describes a template-free solution-phase method to synthesize well-aligned nickel nanochains under applied magnetic fields. The authors report that nanochain size and morphology can be tuned by reaction temperature and magnetic field conditions, and explain alignment via magnetic…

This condensed-matter study investigates highly oriented pyrolytic graphite under very strong magnetic fields at low temperature. It reports a magnetic-field-induced charge density wave transition and a subsequent sign reversal of the Hall coefficient from negative to positive. The reported angular dependence…

This paper is a review of two-dimensional electron dynamics in microscopically inhomogeneous magnetic fields, focusing on magnetic potentials varying on scales smaller than the mean free path. It covers early work on localization in random magnetic fields, methods to fabricate magnetic potentials, and drift-diffusion…

This laboratory study investigates how magnetic field and pressure affect valence and magnetic transitions in the compound EuPtP. High-field analysis suggests a mixed valence state at low temperature and discontinuous changes in Eu2+ fraction at two transition temperatures. Pressure increases the transition…

Jan 1, 2007
This theoretical paper investigates Beresinskii-Kosterlitz-Thouless vortex physics in two-dimensional superconductors under an external magnetic field using a sine-Gordon field-theory approach. The authors state that the model yields a straightforward definition of field-induced magnetization. They also report that…
