Title: Drag force measurement: A means for determining hysteresis loss

Abstract

A method for determining hysteresis losses in thin strips of soft magnetic materials is described. It is based on the measurement of a drag force which arises with the movement of the sample through the strong field existing in the space near a permanent magnet. Not associated with macro eddy currents, the force is shown to originate from the magnetic hysteresis of the material, having, in fact, an amplitude equal to the product of hysteresis loss and the area of the sample cross section. Correlation within 18% with the measurements made by conventional methods is shown for a wide range of experimental materials.

  • It was shown that spontaneous polarization of solid solutions of Ba(Ti, Sn)O/sub 3/ and Ba(Ti, Zr)O/sub 3/ decreases as the content of BaTiO/sub 3/ decreases; the spontaneous poiarization of solid solutions of (Ba, Sr)TiO/sub 3/ decreases as the amount of SrTiO/sub 3/ is increased up to 40 wt.%, and increases as the amount of SrTiO/sub 3/ is increased from 40 to 50 wt.%. It is also shown that the coercive forces and hysteresis loss decrease during the transition from tetragonal phase into orthorhombic and from the orthorhombic into rhombohedron form. Within the limits of each phase the coercive forces andmore » hysteresis loss increase as the temperature is lowered. (tr-auth)« less
  • The ion drag force acting on a small absorbing grain has been calculated in highly collisional plasma with slowly drifting ions taking into account plasma production and loss processes in the vicinity of the grain. It is shown that the strength of the plasma production and loss mechanisms not only affects the magnitude of the ion drag force, but also determines the direction of the force. The parameter regimes for the ''positive'' and ''negative'' ion drag forces have been identified. In addition, the qualitative features of the electric potential distribution around the grain in isotropic conditions (in the absence ofmore » the ion drift) are investigated.« less
  • The ion drag force acting on a small absorbing spherical grain has been calculated analytically in highly collisional plasma with slowly drifting ions taking into account plasma production and loss mechanisms in the vicinity of the grain. It is shown that both the magnitude and direction of the ion drag force are strongly influenced by the plasma production and loss mechanisms. The parameter regimes for the 'positive' and 'negative' ion drag forces acting on an absorbing grain have been identified.
  • The dependence of on-field and off-field hysteresis loop shape in Piezoresponse Force Microscopy (PFM) on driving voltage, Vac, is explored. A nontrivial dependence of hysteresis loop parameters on measurement conditions is observed. The strategies to distinguish between paraelectric and ferroelectric states with small coercive bias and separate reversible hysteretic and non-hysteretic behaviors are suggested. Generally, measurement of loop evolution with Vac is a necessary step to establish the veracity of PFM hysteresis measurements.
  • Complementary measurement and simulation methods are described that enable rapid characterization of drag force coefficient/mass ({ital C}{sub {ital d}}/{ital m}) ratios of individual particles in the 20 to 200 {mu}m size range. Individual particles are suspended in a charge trap known as an electro-dynamic balance (EDB). A step change is applied to the EDB end cap voltage to stimulate a dynamic response of the particle from an initial steady state. The resulting transient response is measured by means of a high speed, two-dimensional diode array and imaging system which provides an analog output indicating particle position along the EDB centermore » axis at frame rates of 6200 per second. A particle dynamic model (PDM) is developed to simulate trajectories of particles in the EDB. The PDM is a force balance simulation which accounts for field forces, gravitational forces, and drag forces acting on a particle. Simulations are performed using particle {ital C}{sub {ital d}}/{ital m} ratio as a fit parameter to match model outputs with measurements. Data are presented for polystyrene and glass spheres showing that {ital C}{sub {ital d}}/{ital m} ratios can be determined with an uncertainty less than {plus_minus}5 percent. When applied to characterize spheres, particle densities, diameters, and mass can be accurately determined. The methods described are an integral part of a powerful new system that enables detailed characterization of mass, density, external surface area, and volume of irregular shaped particles in the 20 to 200 {mu}m size range.« less
