Iron Loss and Hysteresis Properties under High-Temperature Inverter Excitation

Electronic Excitation and Thermodynamic Properties of High Temperature Gases

Different cut-off criteria of partition functions have been utilized in order to evaluate the con­ tribution of electronic excitation to thermodynamic properties of high temperature gases (5000 °K to 35 000 °K, 1 0 -21 0 atm ). It is shown that properties of single species are strongly affected by the cut-off criterion adopted, i. e. the contribution of electronic excitation to these properties...

High-Temperature Wide Thermal Hysteresis of an Iron(II) Dinuclear Double Helicate

Two new dinuclear iron(II) complexes (1·PF6 and 1·AsF6) of the general formula [Fe2(L2)2](X)4·nH2O·mMeCN (X = PF6, n = m = 1.5 for 1·PF6 and X = AsF6, n = 3, m = 1 for 1·AsF6) have been prepared and structurally characterized, where L2C3 is a bis-1,2,3-triazolimine type Schiff-base ligand, 1,1′-[propane-1,3-diylbis(1H-1,2,3-triazole-1,4-diyl)]bis{N-[2-(pyridin-2-yl)ethyl]methanimine}. Single cr...

Magnetic Cluster Expansion Model for High-Temperature Magnetic Properties of Iron and Iron-Chromium alloys

HIGH TEMPERATURE ELASTIC PROPERTIES OF REFRACTORY MATERIALS

Abstract: A pulse-echo technique, based on ultrasonic "long-bar" mode (LBM) velocity measurements, working up to 1700°C is described. Magnetostrictive transducers and ultrasonic lines used in a 40-85 kHz frequency range are detailed. The conditions of choice of fundamental parameters (frequency, line geometry, sample size) are discussed in relation with the nature and the microstructure of ...

Hysteresis and noise from electronic nematicity in high-temperature superconductors.

An electron nematic is a translationally invariant state which spontaneously breaks the discrete rotational symmetry of a host crystal. In a clean square lattice, the electron nematic has two preferred orientations, while dopant disorder favors one or the other orientations locally. In this way, the electron nematic in a host crystal maps to the random field Ising model. Since the electron nema...
