A simple mass producible detection array for terahertz radiation has been designed and fabricated. The 1 mm times 1 mm pixels consist of a 0.5 mm times 0.5 mm thin-film absorber on a membrane, supported by 0.28-mm-wide silicon separation beams. Therm

The resonance line shift of a series of A-15 structures (V 3 Pt, V 0.76 Pt 0.24 and V 0.62 Ir 0.38 ) is measured as a function of temperature in the superconducting state. A method will be described to separate the contribution of the diamagnetism of

Photon spin-lattice relaxation data in magnetic crystals can be interpreted in terms of two-spin correlation functions of the electron spin system. In this paper we present experimental results on the compound CuSO4.5H2O, for temperatures well below

Zero field spontaneous magnetization curves have been determined by nuclear magnetic resonance technique. Fitting these curves on numerical calculations on a renormalized spin wave model yields values of the anisotropy in the exchange interaction ran

The magnetic behaviour of a system of weakly coupled S = 1 2 antiferromagnetic Heisenberg lineae chains in external field is discussed. From NMR experiments detailed information is obtained concerning the influence of the low dimensionality of the ma

A description of the nuclear spin lattice relaxation in insulating Heisenberg magnets is outlined. Nuclear spin lattice relaxation times are expressed in spectral densities φ α ij (ω) using measured nuclear magnetic hyperfine and electric quadrupo

The ground state of the magnetic copper ion and the transfer of unpaired spin to the ligands is described taking into account the influence of the crystalline field and the partly covalent bonding with three inequivalent pairs of ligands. Experimenta
