We have investigated the propagation of surface acoustic waves in ultrathin ordered organic films. For this purpose cadmium stearate Langmuir-Blodgett films were deposited on YZ LiNbO 3 crystals. By measuring the wave attenuation, changes in the conf

The coherent dynamics of atomic tunneling states in (KBr${)}_{1\mathrm{\ensuremath{-}}\mathit{x}}$(KCN${)}_{\mathit{x}}$ crystals in the concentration range 0.001\ensuremath{\ge}x\ensuremath{\ge}0.18 have been investigated at low temperatures with tw

We have investigated the low-temperature behaviour of the dielectric constant of the mixed crystal (KBr)1-x(KCN)x for x = 0.01 and x = 0.001. The experiments were performed at microwave frequencies between 150 and 1227 MHz in the temperature range fr

Acoustic plate mode (APM) devices have been used as detectors in liquid environments. One of the primary detection mechanisms in such devices is mass loading. In the present work, the potential of APMs as mass sensitive biosensors is evaluated using

The attenuation of surface acoustic waves (SAWs) on YZ‐LiNbO3 crystals, coated with an aluminum layer of several hundred angstroms, has been measured as a function of temperature in the range from 0.3 K to room temperature. A peak in attenuation wa

It is well known that the low temperature thermal, acoustic and dielectric properties of CN− doped KBr crystals are dominated by atomic tunneling systems. To study the dynamic behavior of the CN− tunneling states we have performed low temperature

For a long time the investigation of materials with ultrasonic waves has been a well established technique. The potential of this method resides in the fact that it is sensitive to small variations in mass density or of the elastic constants of the m

A few years ago surprising magnetic field effects were found in non- magnetic glasses at low temperatures (≈ 10 mK). It has since been established that this effect can be attributed to the tunnelling motion of particles carrying nuclear quadrupole

Using a triple-pass plane and a confocal Fabry-Pérot interferometers in tandem, we have constructed a Brillouin spectrometer with a frequency resolution of 10(8) and a contrast of more than 10(10). Our system is controlled and fully stabilized by a
