Magnetic orientation of benzophenone crystals in fields up to 80.0 KOe

Article Abstract:

A model is developed to analyze the growth of benzophenone crystals in magnetic field intensities of up to 80.0 KOe. The crystals were grown in a solution of benzophenone dissolved in hot n-hexane which was allowed to stand for five hours. Results show that the probability that crystals are oriented increases with increasing field intensity. The orientation also conforms with the Boltzmann distribution for crystals with different magnetic energies.

Movement and diffusion of paramagnetic ions in a magnetic field

Article Abstract:

The magnetic movement and thermal diffusion of paramagnetic ions in a magnetic field are studied. The [Cu.sup.2+] ions is found to move in a large group composed of [Cu.sup.2+] ions and H2O molecules and the size of the group is approximately found to be of 4.6 micro m diameter by the analysis of the drift velocity of the group and the [Cu.sup.2+] ion concentration in the group.

On the movement of paramagnetic ions in an inhomogeneous magnetic field

Article Abstract:

The movement of transition-metal ions was observed in an inhomogeneous magnetic field. The solution containing Cr(super 3+), Mn(super 2+), Co(super 2+), Ni(super 2+), and Cu(super 2+) ions was spotted on a silica gel support and exposed to a magnetic field of 410 kOe(super 2) cm(super -1) intensity x gradient.
