Temperature dependent photoresponse of thin La0.75Ca0.25MnO3films to visible and near-infrared laser radiation has been studied in a wide temperature range. At temperatures below 50 K, we have found a non-bolometric contribution to the response which

We have measured the ac impedance of Y-Ba-Cu-O thin films in a magnetic field of 0.55 T and in the frequency range from 100 kHz to 500 MHz. At the temperature of the dc vortex-glass transition but in the ac linear regime, we find scaling behavior of

We present study of stimulated THz emission from uniaxially strained Ge at low electric field. The cw regime was reached at electric field below 10 V/cm. The carrier population inversion is a result of capture and emission of free holes at strain-ind

We demonstrate the operation of a ‘‘Josephson Broadband Spectrometer’’ (JOBS) with a frequency range and bandwidth of 1 THz. The JOBS uses the inherent frequency tuning of the Josephson oscillations (f=2 eV/h) as a probe of the complex impeda

We have demonstrated mutual phase locking of two YBa2Cu3O7 Josephson junction oscillators in the frequency range from 0.2 to 1 THz. A maximum power of 0.2 μW was delivered to a distributed 8 Ω load at 0.7 THz. The corresponding dc locking current,

We have fabricated high quality, submicron sized Nb/PbBi window tunnel junctions suitable for sub-mm wave applications. The junctions had critical current densities in the range 20–4*104 A/cm2 and reproducible areas from 0.03 to 5 μm2. The junctio

A Josephson effect heterodyne mixer for the millimeter wave band was investigated employing high-T(c) GdBaCuO point contacts. Mixer performance was in qualitative agreement with theory. A mixing response was observed up to 55 K, the highest operating

We have observed r.f.-induced Josephson steps using 70 GHz radiation in point contacts comprised of samples of YBaCuO which had a Tc ~ 80 K. Low junction resistances (~ 100 Ω) produced d.c. supercurrents of (2÷5) μA. At a temperature of 4.2 K, r.f
