In a previous neutron scattering study, we had observed that the TA1[ξξ0] phonon softening in L12-ordered ferromagnetic Fe72Pt28 Invar is pronounced at the zone boundary M-point and leads to an antiferrodistortive phase transition at low temperatur

We report about the physical and chemical origin of the quick loss of intensity of certain argon/mercury cold cathode illumination tubes, especially those manually coated with luminous powder using the European powder technology. The reason is the di

The ferromagnetic interstitial iron compound Fe(3)C (cementite) is expected to have Invar properties, whereby a high-moment to low-moment transition should occur when the atomic volume is reduced below a critical value. We, therefore, examine the pre

We have performed inelastic neutron scattering measurements of the long‐wavelength spin wave excitations of both ordered and disordered Fe72Pt28 single crystals below their critical temperatures, TC=510 and 375 K, respectively. The spin waves follo
We report measurements of the thermal conductivity on two amorphous Ni 72 Si 8 B 20 samples of different thicknesses 90 μm and 25 μm in the temperature range between 0.3 K and 25 K. The thickness of the ribbons (Vitrovac 0080) was correlated to the

The discrepancy in Invar alloys between the magnetic excitation spectrum determined directly by neutron scattering and that inferred from magnetization measurements may be due to the significant contribution of longitudinal spin fluctuations to the e

The impurity contribution to the resistivity in zero field Δρ(T) of dilute hexagonal single crystals of ZnMn, CdMn and MgMn has been studied in the mK range on samples cut parallel (‖) and perpendicular (⊥) to thec-axis, using a SQUID technique
