On the Total Magnetic Moment of Large Atoms in Strong Magnetic Fields
We look at the magnetisation of neutral atoms in large magnetic fields. Asymptotic formulas for the energy exist with high precision in different regions depending on how large the nuclear charge Z is compared to the magnetic field strength B. All these formulas take the splitting of the kinetic energy into Landau levels as the principal feature and then treat the electric potential as a pertur...
متن کاملProton β Decay in Large Magnetic Fields
A delicate interplay between the anomalous magnetic moments of the proton and neutron makes, in magnetic fields B ≥ 2 × 10 T, the neutron stable and for fields B ≥ 5 × 10 T the proton becomes unstable to a decay into a neutron via β emission. Limits on the field strengths for which these arguments hold are presented and are related to questions of vacuum stability in the presence of such fields...
متن کاملAccretion Disks in Large-scale Magnetic Fields
This paper presents a survey of a set of simulations of accretion disks orbiting a rapidly rotating Kerr black hole and embedded in a large-scale initial magnetic field. Each simulation uses a common state for the initial torus, including an MRI seed-field consisting of poloidal loops along isodensity contours, and differ only in the strength of the initial large-scale magnetic field in relatio...
متن کاملLarge magnetoresistance with low saturation fields in magnetic/magnetic superlattices
Ni/Co multilayers grown by molecular beam epitaxy are found to exhibit a magnetoresistance AR/R at liquid helium temperature as large as 8.2%, with saturation fields AH-22 Oe and a sensitivity (AR/R)/(2AH)=O. 19% Oe-‘. The highest room temperature sensitivity obtained to date in this system is 0.18% Oe-’ and at 4.2 K is 0.29% Oe-‘. This demonstrates that high values of the sensitivity can be ac...
متن کاملObserving Magnetic Fields on Large Scales
Observations of magnetic fields on scales up to several Mpc are important for understanding cluster and largescale structure evolution. Our current census of such structures is heavily biased – towards fields of several μG, towards fields in deep potential wells, and towards high inferred field strengths in cooling flow and other clusters from improper analysis of rotation measure data. After r...
