国際学会体験談（Julia Angelさん＠ミュオンスピン共鳴研究室）
|
Reports:I had participated in the conference organized by ITS (Sepuluh Nopember Institute of
Technology), UNPAD (Padjadjaran University), ITB (Bandung Institute of
Technology), UI (University of Indonesia), UGM (Gadjah Mada University), and
RIKEN as a contributed speaker/poster presentation. During the conference, I can
discuss with other professors, students, and researchers. I am chosen as one of the best
poster presenters, although I just had a simple discussion with a few of them. I talk
about magnetic properties of hole-doped pyrochlore iridate (Y1-x-yCuxCay)2Ir2O7
investigated by resistivity, XPS and muon-spin relaxation measurements. We found in
the non-doped system that the magnetic ordering of Ir spins which was accompanied
by the metal-insulator transition (MIT) occurred at around 157 K and disappeared in
the doped system in which MIT seems to disappear. We suggest from the current study
that a quantum critical point which shows a change in the electronic ground state from
insulating to metallic to exist in (Y1-x-yCuxCay)2Ir2O7 system. The manuscript of this is
currently in the process of awaiting editor’s decision to publish and will be published
in Key Engineering Materials, which is published by Trans Tech Publications and
indexed by SCOPUS, SCImago Journal Country Rank, and others.
Message to younger student:Join and participate in many international conferences in aboard related to your study
as much as possible. It can improve your English skills, your sciences and build your
confidence. You may meet good teachers in there! You can also publish your research
even if it just still in the initial stage. Having much publication can brighten your future
as a scientist for sure!
