Anisotropy of electronic heat and charge transport provides an insight into critical magnetic phenomena, as revealed in non-Fermi-liquid transport properties.
Some superconductors exhibit avalanche - like dynamics usually associated with thermo-magnetic instabilities of the vortex lattice. We study this behavior using magneto-optical, DC and AC magnetization, transport and thermal techniques.
Precise measurements of the magnetic penetration depth are performed at low temperatures and magnetic fields up to 9 Tesla by using a tunnel-diode diode resonator.
NV-centers in diamond optical magnetometry utilizes completely new “quantum sensing” where we interrogate quantum states of the NV center and use it for sensing of extremely weak magnetic fields.
Quantum critical points inside of superconducting dome of unconventional superconductors can be accessed by investigating pressure dependence of penetration depth.
The same technique is used to measure temperature-dependent dynamic magnetic response in materials exhibiting apparent transition in their ground state.
Direct visualization of the magnetic fields (based on magneto-optical Faraday effect) is used to study real-time formation and evolution of the intermediate state patterns in stress- and defect- free type-I superconductors.
Properties of anisotropic materials are frequently averaged by formation of structural domains. Detwinning by the application of uniaxial stress enables formation of monodomain sample and enables study of intrinsic anisotropy.
