Construction techniques for adiabatic demagnetization refrigerators using ferric ammonium alum
We describe techniques used to fabricate the cold stage of an adiabatic demagnetization refrigerator that uses the paramagnetic salt ferric ammonium alum. We discuss the design of a leak-tight housing for the salt as well as a technique for growing ferric ammonium alum crystals that results in a housing filled with > 98% refrigerant. These techniques have proven to be reliable in creating robus...
متن کاملAnisotropy of the photo-elastic effect in Nd:KGd(WO4)2 laser crystals
The anisotropy of thermal lensing and the photo-elastic effect is characterized for diode-pumped Nd:KGd(WO4)2 crystals cut along the Np and Ng optical indicatrix axes and along its optical axis, O = Ng+43°, at a laser wavelength of 1067 nm. Distortions in the spatial profile of output laser beam are analyzed. The thermal lens is astigmatic; the orientation of its principal meridional planes, A ...

متن کاملPhase-field crystals with elastic interactions.
We report on a novel extension of the recently introduced phase-field crystal (PFC) method [Elder, Phys. Rev. Lett. 88, 245701 (2002)10.1103/PhysRevLett.88.245701], which incorporates elastic interactions as well as crystal plasticity and diffusive dynamics. In our model, elastic interactions are mediated through wave modes that propagate on time scales many orders of magnitude slower than atom...
متن کاملElastic crystals with a triple point
The peculiar behavior of active crystals is due to the presence of evolving phase mixtures the variety of which depends on the number of coexisting phases and the multiplicity of symmetryrelated variants. According to Gibbs’ phase rule, the number of phases in a single-component crystal is maximal at a triple point in the p-T phase diagram. In the vicinity of this special point the number of me...
