Journal ArticleDOI
Linear Magnetoresistance Caused by Mobility Fluctuations in n-Doped Cd3As2
Arjun Narayanan,Matthew Watson,S. F. Blake,N. Bruyant,Loïc Drigo,Yulin Chen,D. Prabhakaran,Binghai Yan,Claudia Felser,Tai Kong,Paul C. Canfield,Amalia I. Coldea +11 more
TL;DR: From the observed quantum oscillations, the bulk three-dimensional Fermi surface is determined having signatures of Dirac behavior with a nontrivial Berry phase shift, very light effective quasiparticle masses, and clear deviations from the band-structure predictions.
Journal ArticleDOI
Emergence of the nematic electronic state in FeSe
Matthew D. Watson,Timur K. Kim,Amir A. Haghighirad,N. R. Davies,Alix McCollam,Arjun Narayanan,S. F. Blake,Yulin Chen,Saman Ghannadzadeh,Andrew J. Schofield,Moritz Hoesch,Christoph Meingast,T. Wolf,Amalia I. Coldea +13 more
TL;DR: In this paper, the authors observe the changing Fermi surface, the position of the lowest energy electronic excitations, as well as the propensity towards nematic order and its manifestation under strain.
Journal ArticleDOI
The Key Ingredients of the Electronic Structure of FeSe
TL;DR: In this paper, the authors provide an overview of the current understanding of the electronic structure of FeSe, focusing in particular on its low-energy electronic structure as determined from angular resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements of single-crystal samples.
Journal ArticleDOI
Evolution of the Fermi Surface of BaFe2(As1-xPx)2 on Entering the Superconducting Dome
Hiroaki Shishido,A. F. Bangura,Amalia I. Coldea,S. Tonegawa,Koji Hashimoto,Shigeru Kasahara,Pmc Rourke,Hiroaki Ikeda,Takahito Terashima,Rikio Settai,Yoshichika Onuki,D Vignolles,C. Proust,B Vignolle,Alix McCollam,Yuji Matsuda,Takasada Shibauchi,Antony Carrington +17 more
TL;DR: It is found that the volumes of electron and hole Fermi surfaces shrink linearly with decreasing x, and there is a strong increase in the quasiparticle effective mass as x is tuned toward the maximum T{c}.
Journal ArticleDOI
Fermi Surface of Superconducting LaFePO Determined from Quantum Oscillations
Amalia I. Coldea,J. D. Fletcher,Antony Carrington,James Analytis,A. F. Bangura,J.-H. Chu,A. S. Erickson,Ian R. Fisher,Nigel E. Hussey,Ross D. McDonald +9 more
TL;DR: The Fermi surface is in broad agreement with the band-structure calculations with the quasiparticle mass enhanced by a factor approximately 2.5, suggesting proximity to a spin or charge density wave instability.
