Nanophotonic Optomechanical Devices for Torque Magnetometry
Torque magnetometry is a powerful and sensitive method for studying intricate mesoscopic magnetic events inside magnetic materials using nanomechanical resonators. Over the years, the field of cavity optomechanics has demonstrated ever increasing sensitivity, with measurements limited by the …

Anisotropic behaviour of magneto-electric coupling in multiferroic composites
… of the magnetic anisotropy study, a modified torque magnetometry method has been developed to enhance the identification of the anisotropy directions in magnetically soft samples, as well as a method by which torque magnetometry can be approximated using the in-field direction component of …

Magnetic and thermal properties of metallic antiferromagnetic materials
… property of antiferromagnetic materials. Torque magnetometry measurements of Fe2As were performed. We reported that the four-fold magnetocrystalline anisotropy K22 in the (001)-plane of Fe2As is K22 = −150 kJ/m^3 at T = 4 K, much smaller than the perpendicular magnetic anisotropy of …

High magnetic field study of strongly correlated electron systems
… and underdoped cuprates - as well as high field torque magnetometry and magnetisation measurements on the Kondo insulator samarium hexaboride. Shubnikov-de Haas oscillations observed in the former further our understanding of the nature of the normal states of these high temperature …

X-Ray scattering investigations of subtle ordering in correlated materials
… couple strongly to this change. Additionally, torque magnetometry and x-ray diffraction suggest a breaking of C4 rotational symmetry. We directly study the lattice through x-ray scattering. We see no change of the acoustic phonon dispersions or of the phonon lifetimes from the HO transition. …

Magnetic properties of graphite and Bi2Sr2CaCu2O8+δ
Graphite is the strongest diamagnet of all known materials to date. Recent studies of the thickness dependence of the resistance of graphite have demonstrated the heterogeneity of the charge distribution in bulk graphite and prompted the study of its magnetic properties. The studies of the …

Explorations of domain walls and half quantum vortices in unconventional superconductors
… ring-shaped samples of Sr2RuO4, using cantilever torque magnetometry. We briefly review the experimental technique and the experimental results that have emerged from its application to Sr2RuO4. We then discuss two possible scenarios for the theoretical interpretation of the observed half integer …
