Low temperature magnetism of KAgF3
John M. Wilkinson, Stephen J. Blundell, Sebastian Biesenkamp +7
KAgF is a quasi one-dimensional quantum antiferromagnet hosting a series of intriguing structural and magnetic transitions. Here we use powder neutron diffraction, SR spectr…
Muon-spin relaxation investigation of magnetic bistability in a crystalline organic radical compound
Alberto Hernandez-Melian, Benjamin M. Huddart, Francis L. Pratt +5
We present the results of a muon-spin relaxation (SR) investigation of the crystalline organic radical compound 4-(2-benzimidazolyl)-1,2,3,5-dithiadiazolyl (HbimDTDA), in wh…
Beyond Single Tetrahedron Physics of Breathing Pyrochlore Compound Ba3Yb2Zn5O11
Rabindranath Bag, Sachith E. Dissanayake, Han Yan +11
Recently a new class of quantum magnets, the so-called breathing pyrochlore spin systems, have attracted much attention due to their potential to host exotic emergent phenomena. He…
Ubiquitous Spin Freezing in the Superconducting State of UTe2
Shyam Sundar, N. Azari, M. Goeks +17
In most superconductors electrons form Cooper pairs in a spin-singlet state mediated by either phonons or by long-range interactions such as spin fluctuations. The superconductor U…
A.C. susceptibility as a probe of low-frequency magnetic dynamics
C. V. Topping, S. J. Blundell
The experimental technique of a.c. susceptibility can be used as a probe of magnetic dynamics in a wide variety of systems. Its use is restricted to the low-frequency regime and th…
Entanglement between a muon spin and nuclear spins
Pietro Bonfà, Jonathan Frassineti, John M. Wilkinson +9
We report on the first example of quantum coherence between the spins of muons and quadrupolar nuclei. We observe this effect in vanadium intermetallic compounds which adopt the A1…
