Dielectric and Magnetic Anomalies in α-MnS Single Crystals at Applied Magnetic Fields

AbstractWe report the magneto-conductivity analysis of Bi2Se3 single crystal at different temperatures in a magnetic field range of ± 14 T. The single crystals are grown by the self-flux method and characterized through X-ray diffraction, Scanning Electron Microscopy, and Raman Spectroscopy. The single crystals show magnetoresistance (MR%) of around 380% at a magnetic field of 14 T and a temperature of 5 K. The Hikami–Larkin–Nagaoka (HLN) equation has been used to fit the magneto-conductivity (MC) data. However, the HLN fitted curve deviates at higher magnetic fields above 1 T, suggesting that the role of surface-driven conductivity suppresses with an increasing magnetic field. This article proposes a speculative model comprising of surface-driven HLN and added quantum diffusive and bulk carriers-driven classical terms. The model successfully explains the MC of the Bi2Se3 single crystal at various temperatures (5–200 K) and applied magnetic fields (up to 14 T).

We have extended the low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 600 p.p.m. manganese from magnetic fields of 9 to 56 kG. The crystal field splitting parameters determined at low magnetic fields also characterizes the magnetic anisotropy at high magnetic fields. Manganese–manganese interaction effects are observed in the magnetic anisotropy at manganese concentrations greater than 300 p.p.m. Low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 164 p.p.m. chromium are reported and indicate a crystal field splitting of 0.16 K for the chromium ion.

Different Depths

Model experiments were made to devise a rapid method for calculating magnetic anomalies of three‐dimensional structures. The magnetic fields of the models were determined using the equipment at the Naval Ordnance Laboratory, White Oaks, Md. An irregularly shaped mass was approximated by an array of prismatic rectangular slabs of constant thickness and varying horizontal dimensions. Contoured maps are being prepared for these magnetic models at different depths and for several magnetic inclinations. The fields of these three‐dimensional structures are obtained by super‐imposing the appropriate contoured maps and adding numerically the effects at each point. The equipment and laboratory methods are described. Theoretical and practical examples are given.
