Spin-orbit coupled heavy metals as a probe of frustrated magnetic systems
ORAL
Abstract
In strongly frustrated magnetic materials, a magnetically ordered state may be suppressed by quantum fluctuations. Such a situation can lead to a quantum spin liquid ground state, where quantum fluctuations a strongly enhanced and lead to long-range entanglement. We realize several experiments to detect signatures of these fluctuations by coupling a magnetically frustrated insulator to an adjacent heavy metal layer. By measuring the evolution of the heavy metal resistivity with temperature and magnetic field, the behavior of these fluctuations can be mapped out. We comment on how our measurements may have relevance to fractional excitations in such systems.
