Effect of doping and disorder on the skyrmion phase dynamics in Zn-doped Cu2O...
Skyrmions are topologically protected, nano-sized objects which have been shown to exist in the spin textures of a range of magnetic materials. As we have recently demonstrated... -
Ionization of Neutral Shallow Donor Muonium in beta-Ga2O3
We propose RF-MuSR experiments focused on confirming the two shallow Mu donor states tentatively observed in single crystalline beta-Ga2O3 samples. This material is a candidate... -
MUSR studies in the spin ferromagnetic Nd0.75Gd0.25Rh3B2 and Nd0.8Tb0.2Al2 al...
We propose to characterize the two magnetic transitions in Nd0.75Gd0.25Rh3B2 and study the spin dynamics and field induced domain rotation via zero field (ZF) and longitudinal... -
Anti-ferromagnetic ordering in the super-oxygenated (La,Sr)2CuO4+y supercondu...
We have obtained a LSCOO x = 0.06 single crystal where neutron diffraction shows field induced anti-ferromagnetic order with an onset field in the range 0-1T and increasing... -
Search for ferromagnetic quantum critical point in the Weyl semimetal Co3-xNi...
The layered half-metal Co3Sn2S2 with a Kagomé lattice in the a-b plane has been recently discovered as a magnetic Weyl semimetal, whose Weyl nodes are only 60 meV above the... -
Dynamics of the quasi-two dimensional XXZ honeycomb antiferromagnet BaNi2V2O8
We propose to perform zero-field muon spin rotation studies of S=1 honeycomb antiferromagnet BaNi2V2O8 which is an ideal physical realization of the quasi-2D magnetic system.... -
A survey of skyrmions
Skyrmions are topological excitations that exist in a variety of magnetic insulators. Here we propose to complete our previous experiment (RB1320198) with the aim of producing a... -
Tuning the skyrmion lattice phase by Mn doping in the Co-Zn-Mn series
Magnetic skyrmions are vortex-like objects characterised by an integer topological winding number. They have been observed in the spin structures of several magnetic materials... -
Spin Dynamics in the isotopically enriched spin ice 162Dy2Ti2O7
In an attempt to study the dynamics of Dy2Ti2O7 measured using muons we have made a sample of 162Dy2Ti2O7 where the 161 and 164 isotopes are reduced to a minimum (max. 0.6% of... -
Skyrmions in applied electric fields
One of the most studied skyrmion-hosting materials is the magnetoelectric insulator Cu2OSeO3 which raises the exciting prospect of manipulating the skyrmion-phase through the...
