Quantum-critical spin dynamics in a Tomonaga-Luttinger liquid studied with muon-spin relaxation
J. S. Möller, T. Lancaster, S. J. Blundell +7
We demonstrate that quantum-critical spin dynamics can be probed in high magnetic fields using muon-spin relaxation (SR). Our model system is the strong-leg spin ladder bis(…
Weak magnetic transitions in pyrochlore Bi2Ir2O7
P. J. Baker, J. S. Moeller, F. L. Pratt +5
Muon spin relaxation measurements on Bi2Ir2O7 show that it undergoes a bulk magnetic transition at 1.84(3) K. This is accompanied by increases in the muon spin relaxation rate and…
Persistent dynamics in the S=1/2 quasi-one-dimensional chain compound Rb4Cu(MoO4)3 probed with muon-spin relaxation
T. Lancaster, P. J. Baker, F. L. Pratt +3
We report the results of muon-spin relaxation measurements on the low-dimensional antiferromagnet Rb4Cu(MoO4)3. No long-range magnetic order is observed down to 50 mK implying a ra…
Probing magnetic order in LiMPO4, M = Ni, Co, Fe and lithium diffusion in LixFePO4
P. J. Baker, I. Franke, F. L. Pratt +4
Muon spin relaxation measurements are reported on three members of the LixMPO4 series. The magnetic properties of stoichiometric samples with M = Ni, Co, Fe, were investigated at l…
Muon spin relaxation investigation of magnetic ordering in the hybrid organic-inorganic perovskites [(CH3)2NH2]M(HCOO)3, M = Ni,Co,Mn,Cu
P. J. Baker, T. Lancaster, I. Franke +6
Muon spin relaxation measurements are reported on samples of dimethylammonium metal formates containing magnetic divalent nickel, cobalt, manganese, and copper ions. These hybrid o…
Experimental demonstration of a new radiation mechanism: emission by an oscillating, accelerated, superluminal polarization current
A. Ardavan, J. Singleton, H. Ardavan +3
We describe the experimental implementation of a superluminal ({\it i.e.} faster than light {\it in vacuo}) polarization current distribution that both oscillates and undergoes cen…
