A high coercivity of 2.6T is achieved in melt-spun Nd–Fe–B isotropic magnet powders by the grain boundary diffusion process using Nd 80 Cu 20 and Nd 82 Al 18 alloys. δM measurements indicate that Nd 2 Fe 14 B nanocrystals are magnetically decoupled after the diffusion process. Transmission electron microscopy revealed that the exchange decoupling is...
Heavily doped poly silicon materials are very important in electronic applications as resistors, interconnects, gate electrodes etc. When used as serpentine resistors in analog applications (say in a switch) the possibility of ‘mutual’ self heating between the fingers leading to reliability concerns is quite significant. This inspires a need to examine the self-heating effects in detail. The electrical...
