We report detailed measurements of the de Haas-van Alphen (dHvA) effect in BaFe_2P_2 which is the end member of the superconducting series, BaFe_2(As_{1-x}P_x)_2. Using high purity samples we are able to observe dHvA oscillations from all the sheets of Fermi surface and hence build up a complete detailed picture of its structure. The results show the existence of a highly warped section of hole surface which may be the origin of the nodal gap structure in this series. Importantly, we find that…

De Haas-van Alphen effect and Fermi surface properties of single crystal CrB2
We report the angular dependence of three distinct de Haas–van Alphen (dHvA) frequencies of the torque magnetization in the itinerant antiferromagnet CrB2 at temperatures down to 0.3 K and magnetic
Quantum oscillation studies of the Fermi surface of iron-pnictide superconductors

Accurate determination of the Fermi surface of tetragonal FeS via quantum oscillation measurements and quasiparticle self-consistent GW calculations
We perform de Haas-van Alphen measurements and quasiparticle self-consistent \textit{GW} (QS\textit{GW}) calculations on FeS. The calculated Fermi surface (FS) consists of two hole and two electron
LiFeAs and LiFeP—Stoichiometric Superconductors
The 122-type superconductor BaFe\(_2\)(As\(_{1-x}\)P\(_x\))\(_2\), discussed in the previous chapter, is a good example of the typical phase diagram found in iron-pnictide superconductors. The parent
Quantum Oscillations in Iron Pnictide Superconductors
Insight into the electronic structure of the pnictide family of superconductors is obtained from quantum oscillation measurements. Here we review experimental quantum oscillation data that reveal a

Magnetism and superconductivity in the layered hexagonal transition metal pnictides
We investigate the electronic and magnetic structures of the 122 (AM$_2$B$_2$) hexagonal transition-metal pnictides with A=(Sr, Ca), M=(Cr, Mn, Fe, Co, Ni) and B=(As, P, Sb). It is found that the

The origin of magnetism and superconductivity in iron-based superconductors is still unclear. Here, by investigating the momentum-dependent particle-hole excitations which quantify the tendency of
A Quantum Critical Point Lying Beneath the Superconducting Dome in Iron Pnictides
Whether a quantum critical point (QCP) lies beneath the superconducting dome has been a long-standing issue that remains unresolved in many classes of unconventional superconductors, notably
