Low-temperature sample orienting device with two degrees of freedom.
We describe a rotating sample holder with two degrees of freedom for galvanomagnetic measurements at low temperatures which allows positioning within 0.5 degrees with a reproducibility of better than 0.5 degrees . The main advantages of our device over other constructions are simple and accurate device adjustment, simple and convenient handling, and simple and quick sample changing.
متن کاملA 31 T split-pair pulsed magnet for single crystal x-ray diffraction at low temperature.
We have developed a pulsed magnet system with panoramic access for synchrotron x-ray diffraction in magnetic fields up to 31 T and at low temperature down to 1.5 K. The apparatus consists of a split-pair magnet, a liquid nitrogen bath to cool the pulsed coil, and a helium cryostat allowing sample temperatures from 1.5 up to 250 K. Using a 1.15 MJ mobile generator, magnetic field pulses of 60 ms...
متن کاملA device for low-temperature crystal reorientation in data collection with the oscillation method
A cold finger attached to the second refrigeration stage of a DE-201 Displex closed-cycle helium refrigerator has been equipped with a miniature DC motor. The device allows reorientat ion of the crystal at low temperature, without remount ing or warming to ambient temperature. The axis around which the crystal is rotated is inclined by 45 ° to the cryostat axis, which gives a 90 ° change in ori...
متن کاملGreen Method for Synthesizing Gallium Nitride Nanostructures at Low Temperature
Gallium nitride (GaN) nanostructures (NS) were synthesized using pulseddirect current plasma enhanced chemical vapor deposition (PDC-PECVD) on quartzsubstrate at low temperature (600°C). Gallium metal (Ga) and nitrogen (N) plasma wereused as precursors. The morphology and structure of the grown GaN NS werecharacterized by field emission scanning electron microscope (FE-SEM), transmissionelectro...
متن کاملLocal Spectroscopy of a Proximity Superconductor at Very Low Temperature
– We performed the local spectroscopy of a Normal-metal–Superconductor (N-S) junction with the help of a very low temperature (60 mK) Scanning Tunneling Microscope (STM). The spatial dependence of the local density of states was probed locally in the vicinity of the N-S interface. We observed spectra with a fully-developed gap in the regions where a thin normal metal layer caps the superconduct...
