Easy-Axis Kagomé Antiferromagnet: Local-Probe Study of Nd${}_3$Ga${}_5$SiO${}_{14}$

Abstract

We report a local-probe investigation of the magnetically anisotropic kagomé compound Nd${}_3$Ga${}_5$SiO${}_{14}$. Our zero-field $\mu$SR results provide a direct evidence of a fluctuating collective paramagnetic state down to 60 mK, supported by a wipe-out of the Ga nuclear magnetic resonance (NMR) signal below 25 K. At 60 mK a dynamics crossover to a much more static state is observed by $\mu$SR in magnetic fields above 0.5 T. Accordingly, the NMR signal is recovered at low $T$ above a threshold field, revealing a rapid temperature and field variation of the magnetic fluctuations.
