Nanoscale (IMAGE) Elhuyar Fundazioa Caption Schematic illustration of gold-magnet hybrid nanostructures illuminated by a laser (red). Due to the polarization-dependent excitation of the plasmonic resonance in the gold part, orthogonal nanoelements can be heated independently. The magnetic moment of the hot magnets (front) can be reversed more easily, resulting in a narrower field-driven magnetic hysteresis loop (left) compared to that of the cold magnets (right).
