Four-Wave Mixing at peV Energy Scales
C. Simon, D. M. Silevitch, T. F. Rosenbaum
We measure the non-linear magnetic susceptibility of the disordered quantum Ising magnet, \lihofour, and demonstrate four-wave mixing due to coherent (anti-)Stokes Raman…

Quantum Barkhausen Noise Induced by Domain Wall Co-Tunneling
C. Simon, D. M. Silevitch, P. C. E. Stamp +1
Most macroscopic magnetic phenomena (including magnetic hysteresis) are typically understood classically. Here, we examine the dynamics of a uniaxial rare-earth ferromagnet deep wi…
