Magnetic order and instability in newly synthesized CoSeAs marcasite
Y. Chen, G. Yumnam, A. Dahal +4
Marcasite class of compounds provide facile platform to explore novel phenomena of fundamental and technological importance, such as unconventional superconductivity or high perfor…
Muon diffusion and electronic magnetism in YTiO
J. A. Rodriguez, A. Yaouanc, B. Barbara +3
We report a SR study in a YTiO single crystal. We observe slow local field fluctuations at low temperature which become faster as the temperature is increased. Our a…
Absence of static magnetic order in lightly-doped Ti1-xScxOCl down to 1.7 K
A. A. Aczel, G. J. MacDougall, F. L. Ning +5
Impurity-induced magnetic order has been observed in many quasi-1D systems including doped variants of the spin-Peierls system CuGeO3. TiOCl is another quasi-1D quantum magnet with…
SR studies of the frustrated quasi-2d square-lattice spin system Cu(Cl,Br)La(Nb,Ta)O: evolution from spin-gap to antiferromagnetic state
Y. J. Uemura, A. A. Aczel, Y. Ajiro +15
We report muon spin relaxation (SR) and magnetic susceptibility measurements on Cu(Cl,Br)La(Nb,Ta)O, which demonstrate: (a) the absence of static magnetism in (CuCl)…
Muon Spin Rotation Measurements of Heterogeneous Field Response in Overdoped La2-xSrxCuO4
G. J. MacDougall, A. A. Aczel, R. J. Birgeneau +10
Transverse-field muon spin rotation measurements of overdoped La2-xSrxCuO4 reveal a large broadening of the local magnetic field distribution in response to applied field, persisti…
Impurity-induced singlet breaking in SrCu2(BO3)2
A. A. Aczel, G. J. MacDougall, J. A. Rodriguez +8
We have performed SR studies on single crystals of SrCu(BO), a quasi-two-dimensional spin system with a spin singlet ground state. We observe two different muon site…
Phase separation and suppression of critical dynamics at quantum transitions of itinerant magnets: MnSi and (SrCa)RuO
Y. J. Uemura, T. Goko, I. M. Gat-Malureanu +18
Quantum phase transitions (QPTs) have been studied extensively in correlated electron systems. Characterization of magnetism at QPTs has, however, been limited by the volume-integr…
