At the end of a rush lasting over half a century, in which CMOS technology has been
experiencing a constant and breathtaking increase of device speed and density, Moore's …

Spin insulatronics covers efforts to generate, detect, control, and utilize high-fidelity pure
spin currents and excitations inside magnetic insulators. Ultimately, the new findings may …

Ferroelectrics carry a switchable spontaneous electric polarization. This polarization is
usually coupled to strain, making ferroelectrics good piezoelectrics. When coupled to …

In this review we address the microscopic mechanisms that are involved in the
photogeneration processes of GHz–THz coherent acoustic phonons (CAP) induced by an …

Generation of strain using light is a key issue for future development of ultrasonic devices.
Up to now, photo-induced GHz–THz acoustic phonons have been mainly explored in metals …

Photostrictive effect exhibits a fascinating ability to directly convert light into mechanical
strain, which enables a facile and straightforward approach to realize the wireless and …

Light-matter interactions that lead to nonthermal changes in size of the sample constitute a
photostrictive effect in many compounds. The photostriction phenomenon was observed in …

Ultrashort light pulses induce rapid deformations of crystalline lattices. In ferroelectrics,
lattice deformations couple directly to the polarization, which opens the perspective to …

The magnetic-field-dependent spin ordering of strained BiFeO3 films is determined using
nuclear resonant scattering and Raman spectroscopy. The critical field required to destroy …

We apply ultrafast x-ray diffraction with femtosecond temporal resolution to monitor the
lattice dynamics in a thin film of multiferroic BiFeO 3 after above-band-gap photoexcitation …
