High-pressure and high-magnetic-field study of energy transfer from excitons into local d electrons in a CdTe/(Cd, Mn)Te quantum well structure

“…A plastic DAC was employed in order to avoid increase of sample temperature due to the eddy current during application of the pulsed fields [3]. The column-shaped DAC was 8.9 mm in diameter and 15.5 mm in height.…”

“…To apply pulsed high magnetic fields to a sample under high hydrostatic pressures had been difficult, because increase of the sample temperature cannot be neglected when using conventional metallic pressure cells under pulsed fields. This problem is resolved by using recently developed diamond anvil cells (DACs) with plastic bodies [3]. Taking advantage of high hydrostatic pressures and high magnetic fields, one can adjust the exciton energy and the Mn 2+ 6 A 1 → 4 T 1 excitation band continuously and investigate the energy transfer in diluted magnetic semiconductors in more detail.…”

Superconductivity, incoherence and Anderson localization in the crystalline organic conductor (BEDT-TTF)3Cl2$middot$ 2H2O at high pressures

“…These pressures were achieved using the turnbuckle diamond anvil pressure cell (DAC) shown in figure 3(a). This DAC was designed and built in the National High Magnetic Field Laboratory (NHMFL), Tallahassee and consists of two natural diamonds enclosed in a body of high-tensile BeCu [13]. The highly polished, flat faces of the diamonds are separated by a 65 µm thick, stainless steel gasket coated in alumina.…”
