GROWTH OF HGZNTE BY DIRECTIONAL SOLIDIFICATION IN A MAGNETIC-FIELD

Hg0.84Zn0.16Te crystals were grown vertically by directional solidific ation in a 5 T axial magnetic field. Growth in an identical thermal en vironment but without the presence of magnetic field was also performe d. The ingots were partially grown and quenched to preserve the growth interface shapes. The effects of magnetic damping on the buoyancy-dri ven convective flows in the melt were investigated by examining the qu enched-in interface shapes and by measuring the composition variations along the axial and radial directions of the grown ingots and compari ng them with those of ingots grown without a field.
