Scientists have found through the study of photo-excited precession of magnetization using ultrashort weak laser pulses, that spins in ultra-thin Co/Pd multi-layer films are very susceptible to light; namely, a material that could be a candidate for photo-sensitive magnets.
When researchers dream about electronics of the future, they more or less dream of pouring liquids into a beaker, stirring them together and decanting a computer out onto the table. This field of research is known as self-assembling molecular electronics. But, getting chemical substances to self-assemble into electronic components is just as complicated as it sounds.
Using a method they invented for joining disparate elemental layers into a stable material with uniform, predictable properties, researchers are testing an array of new combinations that may vastly expand the options available to create faster, smaller, more efficient energy storage, advanced electronics and wear-resistant materials.
