Anomalous proximitized transport in metal/quantum magnet heterostructure Bi2Ir2O7/Yb2Ti2O7
Original language description
Fluctuations of quantum spins play a crucial role in the emergence of exotic magnetic phases and excitations. The lack of the charge degree of freedom in insulating quantum magnets, however, precludes such fluctuations from mediating electronic transport. Here, we show that the quantum fluctuations of a localized frustrated magnet induce strong proximitized charge transport of the conduction electrons in a synthetic heterostructure comprising an epitaxial Bi2Ir2O7 ultrathin film on a single crystal of Yb2Ti2O7. The proximity effects are evidenced by the scaling behavior of the Bi2Ir2O7 resistance in correspondence with the dynamic scaling of the dynamic spincorrelation function of Yb2Ti2O7, which is a result of quantum fluctuations near a multiphase quantum critical point. The proximitized transport in Bi2Ir2O7 can be effectively tuned by a magnetic field through suppressing the quantum spin fluctuations (QSFs) as well as inducing transitions via magnetic anisotropy in Yb2Ti2O7. In this paper, we establish a pathway for harnessing QSFs in magnetic insulators with electric transport, offering exciting prospects for potential applications in the realm of quantum spintronics.
