Title: Spin Seebeck effect in insulating SrFeO_3–δ films

Abstract

In SrFeO_3–δ, noncollinear antiferromagnetic spin textures have led to the observation of the topological Hall effect and may give rise to novel magnetic excitations. Here, we measured the spin Seebeck effect in epitaxial, oxygen reduced SrFeO_3–δ films, which are nonferromagnetic and insulating at low temperatures. Here, we detected a spin Seebeck signal below 300K and the signal is enhanced below approximate to 100K, near the ordering temperature of incommensurate antiferromagnetism found in bulk single crystals of SrFeO_3–δ. The spin Seebeck signal increases in magnitude and develops a nonlinear dependence on the magnetic field at lower temperatures. Control experiments were used to verify that the measured signal arises from a spin current and to rule out magnetic proximity effects. Our work shows a detectable spin Seebeck signal in nonferromagnetic insulator SrFeO_3–δ.

Exchange bias effect in Ti doped nanocrystalline SrFeO{sub 3-δ}

Journal Article Sendil Kumar, A., E-mail: sendilphy@gmail.com ; Srinath, S. - AIP Advances

Materials of Ti doped nanocrystalline SrFeO{sub 3-δ} were synthesized through solid state reaction. Detailed magnetization measurements were carried out in zero field cooled (ZFC) and field cooled (FC) conditions. Compounds of SrFe{sub 1-x}Ti{sub x}O{sub 3-δ} (x = 0.1 to 0.3) are found to be spin glass and parent compound is a helical antiferromagnet. Non magnetic Ti{sup 4+} reduces the strength of exchange interactions and the curvature of hysteresis is changed towards concave nature. Exchange bias is observed below the peak temperature (irreversibility in magnetization (T{sub Irr})) in ZFC-FC of SrFe{sub 1-x}Ti{sub x}O{sub 3-δ} (x = 0 to 0.3). The coercivitymore »« less

Observation of Vector Spin Seebeck Effect in a Noncollinear Antiferromagnet

Journal Article Xu, Jinsong ; He, Jiaming ; Zhou, J. -S. ; ... - Physical Review Letters

Spintronic phenomena to date have been established in magnets with collinear moments, where the spin injection through the spin Seebeck effect (SSE) is always along the out-of-plane direction. Here, we report the observation of a vector SSE in a noncollinear antiferromagnet (AF) LuFeO₃, where temperature gradient along the out-of-plane and also the in-plane directions can both inject a pure spin current and generate a voltage in the heavy metal via the inverse spin Hall effect (ISHE). We show that the thermovoltages are due to the magnetization from canted spins in LuFeO₃. Furthermore, in contrast to the challenges of generating, manipulating,more »« less

SrFe{sub 0.9}Ti{sub 0.1}O{sub 3−δ}: A cluster spin glass

Graphical abstract: - Highlights: • Prepared SrFe{sub 0.9}Ti{sub 0.1}O{sub 3−δ} is in nanocrystalline form. • Arrott plot shows absence of spontaneous magnetization which rules out the possibility of long range ferromagnetic order. • AC susceptibility data is evidence of cluster spin glass. • There is no magnetic Bragg's reflection. • By substituting Ti{sup 4+}, helical antiferromagetic SrFeO{sub 3} is transformed to a cluster spin glass. - Abstract: The magnetic ground state of nanocrystalline SrFe{sub 0.9}Ti{sub 0.1}O{sub 3−δ} system has been investigated from 2 K to 300 K using AC Susceptibilty (ACS), magnetization and neutron diffraction measurements.

Structural and magnetic behavior of the cubic oxyfluoride SrFeO{sub 2}F studied by neutron diffraction

Journal Article Thompson, Corey M., E-mail: thompco@mcmaster.ca ; Brockhouse Institute of Materials Research, McMaster University, Hamilton, ON, Canada L8S 4M1 ; Blakely, Colin K. ; ... - Journal of Solid State Chemistry

The oxyfluoride SrFeO{sub 2}F has been prepared via a low temperature route involving the infinite-layer SrFeO{sub 2} and XeF{sub 2}. SrFeO{sub 2}F crystallizes in the cubic space group Pm-3m with disordered oxygen and fluorine atoms on the anion site. Recent reports demonstrated that SrFeO{sub 2}F is antiferromagnetic at room temperature and the zero field cooled and field cooled curves diverge at ∼150 K and ∼60 K, suggesting that the material has a spin glassy magnetic state at low temperatures. In this article, variable-temperature neutron diffraction (4–723 K) was performed to clarify the magnetic behavior observed in this material. Neutron powdermore »« less

Spin Seebeck effect at low temperatures in the nominally paramagnetic insulating state of vanadium dioxide

Journal Article Luo, Renjie ; Zhao, Xuanhan ; Chen, Liyang ; ... - Applied Physics Letters

The low temperature monoclinic, insulating phase of vanadium dioxide is ordinarily considered nonmagnetic, with dimerized vanadium atoms forming spin singlets, though paramagnetic response is seen at low temperatures. Here, we find a nonlocal spin Seebeck signal in VO₂ films that appears below 30 K and that increases with a decrease in temperature. The spin Seebeck response has a nonhysteretic dependence on the in-plane external magnetic field. This paramagnetic spin Seebeck response is discussed in terms of prior findings on paramagnetic spin Seebeck effects and expected magnetic excitations of the monoclinic ground state.
