Thermal Conductivity of Double-Nitrate Crystals below 1°K

Spin-lattice relaxation in cerium magnesium nitrate no partial lattice participation observed

“…With the thermal conduction model we calculated the dispersion and absorption curves at this temperature and field. In the calculations the crystal was represented by a cylinder with a radius of 1.5 mm, a specific heat C L = 1.26 × 10 3 j/m3K [3] and a thermal conductivity h L = 1.50 x 103 W/mK [4]. The spin specific heat C n and the paramagnetic saturation factor K = XT(H)/xT (O) were calculated with the molecular field model as CH = 1.45 × 103 j/m3K and K =0.94.…”

The Collapse of Radiation Stimulated by the Dipole‐Dipole Temperature

“…In the experiment (6) A t >> T 2 and at Ce 25% the ESR line i s not inhomogeneous in the absence of a strong a c field. But in (12) lattice defects a r e reported to occur in CDN. It is shown in (13) that a homogeneous line (the more in the presence of lattice defects) is split intoindividual fine components (in a strong a c field) between which cross-ielaxation occurs "in the iotating coordinate system" with time T that generates phonons in the experiment (6).…”
