In this paper, the effect in structural and magnetic properties of iron doping with concentration of 20% in hafnium dioxide (HfO2) nanoparticles is investigated. HfO2 is a wide band gap oxide with great potential to be used as high-permittivity gate

The generation of coherent light pulses in the extreme ultraviolet (XUV) spectral region with attosecond pulse durations constitutes the foundation of the field of attosecond science [1]. Twenty years after the first demonstration of isolated attosec

Many experiments in attosecond science will benefit from attosecond pulses at high repetition rates with sufficient photon flux for pump-probe experiments. We use 7fs, 800nm pulses from a non-collinear optical parametric chirped pulse amplification (

In this paper, a model based on the molecular field theory is used to fit experimental data of the magnetic hyperfine field (mhf) at nuclei of a magnetic dilute impurity in a magnetic host and determine separately the contributions of the host and th

Hafnium oxide thin films with varying oxygen content were investigated with the goal of finding the optical signature of oxygen vacancies in the film structure. It was found that a reduction of oxygen content in the film leads to changes in both, str

High-Brightness Sources and Light-driven Interactions.
The progress in the development of a high acquisition rate attosecond XUV-IR pump-probe beamline is discussed. A high repetition rate parametric amplifier allows driving the harmonic generation process at a repetition rate of 100 kHz.
