Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and
collective excitations in solids, to drive phase transitions and associated changes in material …

Laser pulses are the shortest stimulus known to control the magnetization of materials and to
switch magnetic devices on the picosecond to femtosecond timescales. Femtosecond laser …

Electrical control of a magnetic state of matter lays the foundation for information
technologies and for understanding of spintronic phenomena. Spin–orbit torque provides an …

Electromagnetic radiation in the terahertz (THz) frequency range is a fascinating
spectroscopic tool that provides resonant access to fundamental modes, including the …

The field of spintronics, or magnetic electronics, is maturing and giving rise to new subfields.
These new directions involve the study of collective spin excitations and couplings of the …

We experimentally demonstrate that the magnetization can be reversed in a reproducible
manner by a single 40 femtosecond circularly polarized laser pulse, without any applied …

Spintronics encompasses the ever-evolving field of magnetic electronics. It is an applied
discipline that is so forward-looking that much of the research that supports it is at the center …

This book emerged from a close collaboration of the authors which started in the fall of 2000.
Early that year one of us (JS) had joined the Stanford faculty after spending nearly 15 years …

In current longitudinal magnetic recording media, high areal density and low noise are
achieved by statistical averaging over several hundred weakly coupled ferromagnetic grains …

Strong light–matter interaction constitutes the bedrock of all photonic applications,
empowering material elements with the ability to create and mediate interactions of light with …
