The general principle of spin-torque nanodevices is depicted in Fig. 1b. A current is injected through the trilayer structure. Under the action of spin torque, magnetization dynamics are generated.

Just like the foot bone's connected to the leg bone, it's only natural to think that a car's engine is connected to its rear wheels. This seemingly reasonable assumption would be wrong—at least in ...

Figure 2. Using HeTRM, energy can be stored in a flexible joint and then released instantly, allowing it to wrap around objects, much like an octopus. Figure 3. Fingers made of soft, rubber-like ...
