Crystal Growth and Characterization of Yb - Based Triangular Lattice Borate

ORAL

Abstract

The quest of understanding the geometrically frustrated magnets in condensed matter physics is an interesting topic as they seem to host a variety of exciting physics such as spin glass, spin ordered and quantum spin liquid state. One of such systems is rare earth borates family which consists of magnetic rare earth ions in a triangular lattice and rare earth ions are magnetically well separated by non-magnetic layers showing exotic ground state. We have successfully synthesized and grown the centimetric sized single crystal of Yb-based borate compound, Ba3Yb(BO3)3. The quality of the grown crystal was confirmed using x-ray/neutron diffraction, magnetometry, and heat capacity. The magnetic study on our grown crystal revealed the presence of anisotropic magnetic interactions between Yb3+ - Yb3+, and heat capacity shows no signature of long range magnetic ordering down to ~50 mK. In this talk, I will share our latest experimental results.
