Superexchange coupling between a dilute Gd3+ probe and orphan spins in a valence-bond glass
Patrick Colgan, Artur Solodovnyk, Jeremy P. Carlo +1
The valence-bond-glass state of the 4d^1 double perovskite Ba2YMoO6 combines Mo^5+ singlets with residual paramagnetic "orphan" spins whose coupling is hard to reach with bulk prob…
Spin-orbit coupling controlled ground states in the double perovskite iridates A2BIrO6 (A = Ba, Sr; B = Lu, Sc)
A. A. Aczel, Q. Chen, J. P. Clancy +11
Iridates with the 5 electronic configuration have attracted recent interest due to reports of magnetically-ordered ground states despite longstanding expectations that their s…
Low-Temperature and Dynamic Magnetism of Highly Frustrated 5d2 Li4MgOsO6 Polymorphs in Comparison with 5d3 Li3Mg2OsO6
Gia T. Tran, Phuong-Hieu T. Nguyen, Charles J. Bloed +12
Geometric magnetic frustration (GMF) has attracted substantial interest due to the exotic physics and rich phase diagrams revealed by the cancellation of normally-dominant magnetic…
Long-Range Magnetic Order in the 5d^2 Double Perovskite Ba2CaOsO6: Comparison with Spin-Disordered Ba2YReO6
C. M. Thompson, J. P. Carlo, R. Flacau +11
The B-site ordered double perovskite Ba2CaOsO6 was studied by d.c. magnetic susceptibility, powder neutron diffraction and muon spin relaxation methods. The lattice parameter is a…
Spin Gap and the Nature of the 4d3 Magnetic Ground State in the Frustrated FCC Antiferromagnet Ba2YRuO6
J. P. Carlo, J. P. Clancy, K. Fritsch +5
The geometrically frustrated double perovskite Ba2YRuO6 has magnetic 4d3 Ru5+ ions decorating an undistorted face-centered cubic (FCC) lattice. This material has been previously re…
Triplet and in-gap magnetic states in the ground state of the quantum frustrated FCC antiferromagnet Ba2YMoO6
J. P. Carlo, J. P. Clancy, T. Aharen +9
The geometrically frustrated double perovskite Ba2YMoO6 is characterized by quantum s=1/2 spins at the Mo5+ sites of an undistorted face-centered cubic (FCC) lattice. Previous low-…
Magnetic phase transition in V2O3 nanocrystals
V. A. Blagojevic, J. P. Carlo, L. E. Brus +7
V2O3 nanocrystals can be synthesized through hydrothermal reduction of VO(OH)2 using hydrazine as a reducing agent. Addition of different ligands to the reaction produces nanoparti…
Study of the ground state properties of using SR
J. Rodriguez, A. A. Aczel, J. P. Carlo +7
is an insulating system where the magnetic Ho ions have an Ising character, and interact mainly through magnetic dipolar fields. We used the muon spin rel…
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)…
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…
