Metallic density of states in the spin liquid RuCl<sub>3</sub>.

POSTER

Abstract

We use resonant line-width spectroscopy and SiN nanocalorimeters to measure specific heat of a small (~1μg mass) RuCl3 sample. The low-temperature limit of C/T is metallic-like, with an extrapolated Sommerfeld coefficient corresponding to a density of states of about 100 mJ/molK2, consistent with Majorana fermions of about 10meV bandwidth. We discuss the field- and angular evolution of this metallic density of states. Finally we examine thermodynamics of the AFM boundary, as well as AFM spin waves in RuCl3.
