"Development of magnetic measurement with nanofabricated pick-up coil for high pressure study with diamond anvil cell"

Presented by Dr. Melike Abliz

Wednesday, April 1, 2009, 3:30 pm — NSLS-II Seminar Room, Bldg. 817

new research area which is important in the materials science and medical
science which is related to cancer treatment that has been recently
recognized in the nano material science.
In this talk we introduce a new type of magnetic measurement method
that we can apply to pick-up a nano volt order magnetic signal from a 100
micron sample for high pressure study. Recently, we succeeded in nano
fabricating a pick-up coil on 300 micron culet of diamond.
High pressure can induce not only structural phase transition but also
electrical phase transition such as superconductor, magnetic ordering, and
volume collapse etc.
Recently, we found a pressure induced volume collapse occurred in a heavy
fermion compound YbIr2Co20 by a synchrotron x-ray diffraction
experiment with high pressure up to 60 GPa. The result is presented in addition to development of magnetic measurement.
