Using a statistical mechanical method we have calculated the magnetization and the initial susceptibility for a ferrofluid composed of fine, uniform spherical particles, taking into account the magnetic dipole interactions in the dimer model under a

The viscosity η of Fe 3 O 4 ferrofluid at volume concentrations in the range ϵ=0.0−0.013 are measured. The corresponding range of values of η is 1.6−1.8 cp. A linear relationship exists between the relative viscosity and the concentration of t

The authors present the effect of intergrain interactions, at T=75 K, on the intragranular critical current density and on the susceptibility of a system consisting of small superconducting grains of GdBa2Cu3O7- delta embedded in solid epoxy. The cri

We study the stability of diluted samples of Fe/sub 3/O/sub 4/ ferrofluid under the action of gravitational field, uniform magnetic field and gradient magnetic field. The dilution was carried out by adding carrier liquid to the ratio (40:1) to the un

The authors derive a relation between the magnetization obtained using a vibrating sample magnetometer (VSM) or a superconducting quantum interference device (SQUID) magnetometer and the magnetization obtained using a Faraday balance (FB). It is show

Absolute total-scattering cross sections ({ital Q}{sub {ital T}}'s) have been measured for positrons and electrons colliding with sodium and potassium in the 3--102-eV range, using the same apparatus and experimental approach (a beam-transmission tec

The effect of bandwidth on Raman backscattering is investigated and an expression for convective amplification is derived, where the effects of collision and phase mismatch were taken into consideration. We found that if we neglect the collision freq

Total cross sections (${Q}_{T}$'s) have been measured for 1--500-eV positrons and electrons scattered by ${\mathrm{O}}_{2}$, ${\mathrm{CH}}_{4}$, and ${\mathrm{SF}}_{6}$ using a beam-transmission technique. The positron ${Q}_{T}$'s are compared with

An analysis of particle interactions in a magnetite ferrofluid has enabled an interpretation to be made of a nonlinear variation of initial susceptibility with concentration, Curie-Weiss behaviour with a negative temperature intercept and a change in
