With the help of a new experimental technique strong anisotropy of the mobility of ions has been observed in hcp4 He crystals. The mobility of positive ions in the direction of the six-fold axis is found to be 200 times higher than in the perpendicular direction. Activation energies of the mobility have been measured in both principal directions. They are equal to: 5.3K in the direction of the C6- axis and 11K in the perpendicular direction. The behaviour of the ions' velocity in the strong electric field regime is also studied as a function of the orientation. [ABSTRACT FROM AUTHOR] |
