摘要:
Camera tubes with a CdTe&sngbnd;Si heterojunction target have been fabricated to observe the electrical effects of the growth striations in dislocation‐free Si crystals grown by the floating‐zone technique. Their video images under a uniform illumination showed spiral patterns due to the growth striations. The origin of the patterns is attributed to the electric fields which are formed locally in the growth striations and drive the photoinduced holes toward the growth direction.

摘要:
Ferrimagnetic resonance within the bubble layer is used to couple two microwave transmission lines. If a bubble is switched into the coupling region which is comparable in size with a bubble domain, the transmitted microwave signal changes. For a 5‐&mgr;m bubble a Zero/One ratio of 6:1 has been obtained. It is also possible to influence the resonance transmission in a reference layer adjacent to the bubble layer by the magnetic stray field of a bubble. At high power levels a nonlinear interaction between the microwaves and the magnetic domains is observed which can be used for bubble generation.

摘要:
High‐field magnetization studies were made from 4 °K to room temperature on rapidly sputtered TbFe2, DyFe2, and SmFe2. At 4.2 °K the magnetic moment resembles that of polycrystal samples, whereas at room temperature it is substantially lower. Huge coercive forces (20–30 kOe) were observed at 4.2 °K. Partial crystallization of TbFe2from the sputtered amorphous state yields high‐energy products and coercivities (> 3 kOe) at room temperature.

摘要:
A survey is given of source materials which can be used to draw ion currents from a Nielsen source. More than 50 different ion species are listed including Pd+, Ir+, Pt+, and Au+. Actual currents obtained during implantation are also reported.
