Low-temperature spin dynamics in the kagome system Pr3Ga5SiO14
Abstract
Neutron-scattering measurements on a single crystal of the distorted kagome system Pr3Ga5SiO14 show that in zero magnetic field the system does not order magnetically at temperatures as low as 35 mK. The specific heat is found to exhibit T2 behavior below 4 K. These results are indicative of a low-temperature two-dimensional dynamically disordered state in this geometrically frustrated antiferromagnet. Complementary in-field NMR experiments …
