Sign-reversal of the in-plane resistivity anisotropy in hole-doped iron.

Here we probe the in-plane electronic anisotropy of electron- and hole-doped BaFe2As2 compounds. Unlike other materials, the resistivity anisotropy behaves very differently for electron- and hole-type dopants and even changes sign on the hole-doped side.... This behaviour is explained by Fermi surface reconstruction in the magnetic phase and. Measurements demonstrate the importance of Hund's-coupling and electronic correlations, especially for hole-doped BaFe2As2, and the inadequacy of a fully localized or fully itinerant description of the 122 family of Fe pnictides. Fe-Kβ X-ray emission spectroscopy measurements reveal an asymmetric doping dependence of the magnetic moments μbare in electron- and hole-doped BaFe2As2. At low.

Local magnetism, magnetic order and spin freezing in the.

At this additional transition ordered magnetic moments reorient from in‐plane to out‐of‐plane alignment associated with a suppression of the orthorhombic distortion. We have studied the magnetic properties of such a representative hole‐doped system, Ba 1- x Na x Fe 2 As 2 with 0.25 ≤ x ≤ 0.40, by neutron diffraction on large.

Magnetic moment evolution and spin freezing in doped BaFe$_{2}$As$_{2.

The magnetic ﬁeld, which would add an additional positive contribution to the LMR below 40 K. One can also see a net change of behavior between the 6% Co magnetic sample and the 7.5% Co nonmagnetic sample, with γ vanishing more rapidly with increasing T in the latter case. The evolution of γ with doping and temperature bears. A difference in the evolution of magnetism upon hole doping has also been reported in INS and RIXS measurements of the spin excitations in Ba 1−x K x Fe 2 As 2 12, 48. Both techniques detected.

Magnetic moment evolution and spin freezing in doped BaFe 2.

Ordered magnetic moments measured (<1 IC magnetic order does indeed develop near optimally. B) also favor an itinerant description. In principle, the propagation vector of the AFM order itself, Q. AFM, should further strengthen the case for itinerant magnetism, as both band structure calculations [10,11] and angle-resolved photo. Spin freezing around From AC magnetic measurement, a partial single ion spin freezing around T f = 33 K at zero magnetic field is observed in (Tb 1−x Eu x ) 2 Ti 2 O 7. [1] The spin-lattice and spin-spin relaxation rates show anomalies due to spin freezing around 3 K as the bulk magnetization. [2] spin freezing behavior. Jul 22, 2021 · The characteristics of structural changes, Fe magnetic moment and electronic structure of TM (TM = Co, Ni, Rh, Pd, Ir and Pt)-doped AFe2As2 (A = Ba, Sr) were studied by first-principles calculations. After the introduction of the dopants, almost all the Fe–Fe distances become longer. The nesting between the electron pockets and the hole pockets is formed. The Fermi level has a tendency to.

Antiferromagnetic spin fluctuations were investigated in the normal states of the parent (x = 0), under-doped (x = 0.04) and optimally-doped (x = 0.06) Ba(Fe 1-x Co x) 2 As 2 single crystals using inelastic neutron scattering technique. For all the doping levels, quasi-two-dimensional antiferromagnetic fluctuations were observed as a broad peak localized at Q = (1/2,1/2,l).

Spin glasses are magnetic systems exhibiting both quenched disorder and frustration, and have often been cited as examples of ‘complex systems.’ At the spin glass “freezing temperature” the spins stop fluctuating but do not exhibit long range orientational order. Geometrically frustrated magnets often exhibit spin glass behavior.
