- Title:
- High magnetic fields and FIB microstructuring as tools for investigation of strongly correlated materials
- Description:
-
f−electron based strongly correlated materials usually host emergent quantum phenomena and are an ideal platform for exploration of exotic states of matter such as unconventional superconductivity, magnetism, strange metallic behavior, quantum criticality etc. In this talk, I will present my work on using high magnetic fields and focused-ion beam microstructuring to investigate novel phases of matter in correlated materials. I will talk about the high-field quantum oscillations and thermodynamic measurements of the heavy fermion antiferromagnet CeRhIn5 , investing the field-induced quantum critical point at 50 T and the nature and origin of the novel field-induced electronic-nematic transition at 30 T. In the second half, I will focus on the anisotropic magnetotransport measurements, performed on a focused ion-beam fabricated microstructured device of the recently discovered multiphase superconductor CeRh2As2. These measurements enabled us to explore the interplay of the multiphase superconducting states with the suggested Quadrupole-density wave phase.
