Published 1996Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A simple, reliable system for long-range translation of scanned probe microscopy (SPM) samples is described. This system could easily be retrofitted to many existing SPMs. The sample is held magnetically onto the scan piezo tube, and is translated by stick-slip motion. The system is very reliable, and provides controllable step size ranging from 20 nm to 1 μm. Three stick-slip drive wave forms are described and tested: sawtooth, cycloid, and an "improved'' cycloid based on the resonance curve of a harmonic oscillator. Computer simulations of the stick-slip process are presented, and are in good agreement with experiment. Together, the experiments and simulations demonstrate that it is essential to consider the resonant response of the piezo when evaluating drive wave forms. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Macroscopic and microscopic switching characteristics are obtained for 100 nm period arrays of Ni nanomagnets with a mean switching field (coercive field) of 710 Oe. Magnetic force microscopy in combination with micromagnetic theory shows that inhomogeneities in the particle shapes result in an intrinsic standard deviation in switching fields of 105 Oe, while the interactions between neighboring nanomagnets broaden the distribution to 276 Oe, equivalent to a squareness of 0.8 in the bulk hysteresis loop. The switching field distribution is consistent with curling as the switching mechanism. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

In der vorliegenden Publikation werden vollständige Gleichungen vorgestellt, die die Druckabhängigkeit beiderBET-Konstanten berücksichtigen und die erfolgreich an Nitrat-Wasser-Systemen getestet wurden, die mono- und divalente Kationen enthalten und deren Konzentrationsbereich von Salzschmelzen bis zu reinem Wasser reicht: [0.500 LiNO3−0.500 KNO3+H2O], [0.467 TlNO3−0.214 CsNO3−0.319 Cd(NO3)2+H2O], [N(C2H5)4NO3+H2O], [0.515 AgNO3−0.485 TlNO3+H2O] und [AgNO3-TlNO3-M(NO3) n +H2O] (M=Na, K, Cs, Cd, Ca;x(AgNO3)/x(TlNO3) wie im vorhergehenden System:x(M) je nach Kation zwischen 0.025 und 0.125). Zusätzlich werden Additivitätsregeln, die sich auf partielle Ableitungen derBET-Parameter bezüglich des Drucks beziehen, vorgestellt.Notes: Summary On the basis of theBrunauer-Emmet-Teller adsorption model extended byStokes andRobinson to concentrated electrolyte solutions, from theStokes-Robinson equation for water activity, and from theAbraham equation for electrolyte activity,Ally andBraunstein have derived equations for the partial excess molar volumes of salt and water in salt-water systems. In their equations, only oneBET parameter is considered to be pressure dependent. In the present publication, complete equations are proposed, taking into account the dependence of bothBET constants on pressure. These equations are tested successfully with nitrate-water systems containing mono and divalent cations over a concentration range from fused salts to water: [0.500 LiNO3−0.500 KNO3+H2O], [0.467 TlNO3−0.214 CsNO3−0.319 Cd (NO3)2+H2O], [N(C2H5)4NO3+H2O], [0.515 AgNO3−0.485 TlNO3+H2O], and [AgNO3−TlNO3−M(NO3) n +H2O] (M=Na, K, Cs, Cd, Ca;x(AgNO3)/x(TlNO3) as in the preceding systemx(M) being varied from 0.025 to 0.125 depending on the cation). Additivity rules which involve the partial derivatives of theBET constants with respect to pressure are also proposed.Type of Medium: Electronic ResourceURL:
