Probing the magnetic phases in the Ni-V alloy close to the disordered ferromagnetic quantum critical point with μSR (2014)
Journal Article
Schroeder, A., Wang, R., Baker, P., Pratt, F., Blundell, S., Lancaster, T., …Möller, J. (2014). Probing the magnetic phases in the Ni-V alloy close to the disordered ferromagnetic quantum critical point with μSR. Journal of Physics: Conference Series, 551(1), https://doi.org/10.1088/1742-6596/551/1/012003

Zero (ZF) and longitudinal field (LF) muon spin relaxation data of the d-metal alloy Ni1-xVx are presented at several vanadium concentrations x below and above the critical xc ≈ 11 % where long-range ferromagnetic (FM) order is suppressed. The clear... Read More about Probing the magnetic phases in the Ni-V alloy close to the disordered ferromagnetic quantum critical point with μSR.

Controlling Magnetic Order and Quantum Disorder in Molecule-Based Magnets (2014)
Journal Article
Lancaster, T., Goddard, P., Blundell, S., Foronda, F., Ghannadzadeh, S., Möller, J., …Manson, J. (2014). Controlling Magnetic Order and Quantum Disorder in Molecule-Based Magnets. Physical Review Letters, 112(20), Article 207201. https://doi.org/10.1103/physrevlett.112.207201

We investigate the structural and magnetic properties of two molecule-based magnets synthesized from the same starting components. Their different structural motifs promote contrasting exchange pathways and consequently lead to markedly different mag...

Dipolar ordering in a molecular nanomagnet detected using muon spin relaxation (2014)
Journal Article
Pratt, F., Micotti, E., Carretta, P., Lascialfari, A., Arosio, P., Lancaster, T., …Powell, A. (2014). Dipolar ordering in a molecular nanomagnet detected using muon spin relaxation. Physical review B, 89(14), Article 144420. https://doi.org/10.1103/physrevb.89.144420

Implanted muons have been used as a local probe to detect the magnetic ordering in the molecular magnetic nanodisk system Fe 19 . Two distinct groups of muon sites are identified from the relaxation data, reflecting sites near the magnetic core and s...

Lattice-Site-Specific Spin Dynamics in Double Perovskite Sr2CoOsO6 (2014)
Journal Article
Binghai, Y., Paul, A. K., Kanungo, S., Reehuis, M., Hoser, A., Többens, D. M., …Jansen, M. (2014). Lattice-Site-Specific Spin Dynamics in Double Perovskite Sr2CoOsO6. Physical Review Letters, 112(14), Article 147202. https://doi.org/10.1103/physrevlett.112.147202

Magnetic properties and spin dynamics have been studied for the structurally ordered double perovskite Sr2CoOsO6. Neutron diffraction, muon-spin relaxation, and ac-susceptibility measurements reveal two antiferromagnetic (AFM) phases on cooling from...

LiZn2Mo3O8 has been proposed to contain S=½Mo3O13 magnetic clusters arranged on a triangular lattice with antiferromagnetic nearest-neighbor interactions. Here, microwave and terahertz electron spin resonance, Li7 nuclear magnetic resonance, and muon...

We investigate the magnetic ordering and dynamics of the stripe phase of La 5/3 Sr 1/3 CoO 4 , a material shown to have an hourglass magnetic excitation spectrum. A combination of muon-spin relaxation, nuclear magnetic resonance, and magnetic suscept... Read More about Stripe disorder and dynamics in the hole-doped antiferromagnetic insulator La5/3Sr1/3CoO4.
