Title: Quantum critical point and ferromagnetic semiconducting behavior in $p$ -type ${FeAs}_{2}$

Abstract

We highlight a method based on itinerant magnetism for finding ferromagnetic semiconductors that can be gate tuned to study quantum critical points. We demonstrate that p-type FeAs ₂ is an example. The complex nonparabolic band structure of this material leads to a ferromagnetic instability when doped, while at the same time allowing for a modest transport effective mass. This leads to an analogy between magnetic semiconductors and thermoelectric materials.

Non-Fermi-liquid types of behavior associated with a magnetic quantum critical point in $Sr {({Co}_{1 - x} {Ni}_{x})}_{2} {As}_{2}$ single crystals

Journal Article Sangeetha, N. S. ; Wang, L. -L. ; Smirnov, A. V. ; ... - Physical Review B

The compound SrCo ₂As ₂ with the body-centered tetragonal ThCr ₂Si ₂ structure is known to remain paramagnetic down to a temperature T = 0.05 K, but inelastic neutron scattering studies have shown that both ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations occur in single crystals. Thus it is of interest to study how the magnetism evolves on doping SrCo ₂As ₂. Previous work on polycrystalline samples of Sr (Co _1-x Ni _x) ₂ As ₂ indicated the development of AFM order for 0 < x ≲ 0.3. Here we studied single crystals of Sr(Co _1-x Ni _x) ₂ As ₂more »« less

Journal Article Vilmercati, Paolo ; Fedorov, Alexei ; Bondino, Federica ; ... - Physical Review. B, Condensed Matter and Materials Physics

A direct and element-specific measurement of the local Fe spin moment has been provided by analyzing the Fe 3s core level photoemission spectra in the parent and optimally doped CeFeAsO1-xFx (x = 0, 0.11) and Sr(Fe1-xCox)2As2 (x = 0, 0.10) pnictides. The rapid time scales of the photoemission process allowed the detection of large local spin moments fluctuating on a 10-15 s time scale in the paramagnetic, antiferromagnetic, and superconducting phases, indicative of the occurrence of ubiquitous strong Hund's magnetic correlations. The magnitude of the spin moment is found to vary significantly among different families, 1.3μB in CeFeAsO and 2.1μBmore »« less

Journal Article Sun, F. ; Zhao, G. Q. ; Escanhoela, Jr., C. A. ; ... - Physical Review B

We investigate doping- and pressure-induced changes in the electronic state of Mn 3d and As 4p orbitals in II-II-V based diluted magnetic semiconductor (Ba _1-x,K _x)(Zn _1-y,Mn _y) ₂As ₂ to shed light into the mechanism of indirect exchange interactions leading to high ferromagnetic ordering temperature (T _c = 230 K in optimally doped samples). A suite of x-ray spectroscopy experiments (emission, absorption and dichroism) show that the emergence, and further enhancement of ferromagnetic interactions with increased hole doping into the As 4p band is accompanied by a decrease in local 3d spin density at Mn sites.
