We measure magnetization changes in a single crystal of the single-molecule magnet Fe8 when exposed to intense, short ( 20μs) pulses of microwave radiation resonant with the m = 10 to 9 transition. We find that radiation induces a phonon bottleneck in the system with a time scale of ∼5μs. The phonon bottleneck, in turn, drives the spin dynamics, allowing observation of thermally assisted resona...

In this study, ZnO thin films were grown by the Successive Ionic Layer Adsorption and Reaction (SILAR) method. The SILAR method is a chemical solution-based consisting of 4 steps: solution, hot water, air deionized water. Our main goal to examine changes in production changing water parameter from these steps. It widely known that synthesis methods their relative parameters have crucial effect ...

METHODS From October 1998 to December 2002 in the Department of Surgery at the University of Pisa, 16 patients ages 18 years or younger (14 girls, 87.5%, and 2 boys, 12.5%; range, 11 to 18; mean age, 15 years, 8 months) underwent a surgical operation with video-assisted technique for thyroid pathology. These patients belong to a larger group of 270 patients treated with this technique. Surgical...

We explore experimentally quantum nondemolition measurements of atomic spin in a hot potassium vapor in the presence of spin-exchange relaxation. We demonstrate a new technique for backaction evasion by stroboscopic modulation of the probe light. With this technique we study spin noise as a function of polarization for atoms with spin greater than 1/2 and obtain good agreement with a simple the...
