Diamond Anvil

A diamond anvil cell (DAC) made of reinforced plastic has been developed for magneto-photoluminescence experiments in pulsed high magnetic fields. Our DAC has a standard and simple structure equipped with a stainless steel gasket. We have made magneto-photoluminescence experiments of CdTe / Cd 0.8 Mn 0.2 Te multiple quantum wells up to 41 T at 4.2 K in the pressure range 0 to 2.3 GPa. We found that the effect of the eddy current heating of the gasket can be negligible small when we use the pulsed field whose duration is a few tens of milliseconds or longer. We have also found that the exciton Zeeman shift strongly depends on the pressure, which can be a manifestation of the enhancement of the sp-d and d-d exchange interactions in the Gd 0.8 Mn 0.2 Te layer by applying high pressures.

Abstract Precise determinations of the thermal conductivity of iron alloys at high pressures and temperatures are essential for understanding the thermal history and dynamics of the metallic cores of the Earth. We review relevant high-pressure experiments using a diamond-anvil cell and discuss implications of high core conductivity for its thermal and compositional evolution.

In situ high pressure energy dispersive X-ray diffraction measurements on layered perovskite-like manganate Ca 3 Mn 2 O 7 under pressures up to 35 GPa have been performed by using diamond anvil cell with synchrotron radiation. The results show that the structure of layered perovskite-like manganate Ca 3 Mn 2 O 7 is unstable under pressure due to the easy compression of NaCl-type blocks. The structure of Ca 3 Mn 2 O 7 underwent two phase transitions under pressures in the range of 0~35 GPa. One was at about 1.3 GPa with the crystal structure changing from tetragonal to orthorhombic. The other was at about 9.5 GPa with the crystal structure changing from orthorhombic back to another tetragonal.
