Ubiquitous order-disorder transition in the Mn antisite sublattice of the (MnBiTe)(BiTe) magnetic topological insulators
M. Sahoo, I. J. Onuorah, L. C. Folkers +12
Magnetic topological insulators (TIs) herald a wealth of applications in spin-based technologies, relying on the novel quantum phenomena provided by their topological properties. P…
Effective decoupling of ferromagnetic sublattices by frustration in Heusler alloys
F. Cugini, S. Chicco, F. Orlandi +10
Magnetic frustration in ferromagnetic metallic systems is unusual due to the long-range and symmetric nature of the exchange interactions. In this work we prove that it is possible…
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…
Frustrated network of indirect exchange paths between tetrahedrally coordinated Co in Ba2CoO4
Ifeanyi John Onuorah, Muhammad Maikudi Isah, Roberto De Renzi +1
We present a detailed study of the electronic and magnetic interactions of Ba2CoO4, structurally very uncommon because of the isolated CoO4 distorted tetrahedral coordination. We s…
Ab initio modeling and experimental investigation of FeP by DFT and spin spectroscopies
Pietro Bonfà, Muhammad Maikudi Isah, Benjamin A. Frandsen +5
FeP alloys have been identified as promising candidates for magnetic refrigeration at room-temperature and for custom magnetostatic applications. The intent of this study is to…
Quantum effects in muon spin spectroscopy within the stochastic self-consistent harmonic approximation
Ifeanyi John Onuorah, Pietro Bonfà, Roberto De Renzi +4
In muon spin rotation experiments the positive implanted muon vibrates with large zero point amplitude by virtue of its light mass. Quantum mechanical calculations of the host mate…
