Abstract

Magnetic hysteresis measurements (4.2⩽T⩽85K, -40⩽H⩽40kOe) carried out in zero field cooled and field cooled Fe₂TiO₅ are found to be consistent with the earlier studies which show this system to be a frustrated one having anisotropic spin glass freezing.

Pseudobrookite based heterostructures for efficient electrocatalytic hydrogen evolution
2021, Materials Reports: Energy
Synthesis of ultrathin heterostructures has received much attention in the recent past due to their unique physical and chemical properties. In this work, we report the synthesis of Fe₂TiO₅–TiO₂ heterostructures using a simple hydrothermal technique employing natural ilmenite as the source. Hierarchically arranged nanostructures with interconnected nano-petals of thickness around 50 nm are obtained. The electrocatalytic properties of the synthesized Fe₂TiO₅–TiO₂ heterostructures are enhanced following the cathodization technique. The observed enhancement in the synthesized materials’ electrocatalytic property can be attributed to the defect-rich Fe_2-xTiO_5-x-TiO_2-x heterostructures. The current approach and technique discussed in this work offer a simple method to synthesize a nanostructured heterostructure material and create defects for enhancing electrocatalytic activity.
Structural and magnetic properties of Fe<inf>2</inf>TiO<inf>5</inf> nanopowders prepared by ball-milling and post annealing

In particular, anyhysteretic behavior and very low effective magnetic moments have previously been disclosed from magnetic measurements and neutron diffraction scattering experiments in Fe2TiO5 single crystals [8]. On the other hand, Srivatava et al. [20] have uncovered the hysteretic magnetic behavior at 4.2 K in a polycrystalline Fe2TiO5 powder sample produced by a ceramic method, in which the hysteresis has a smooth behavior close to the coercive field of ∼200 Oe. In our case in turn, the hysteretic behavior revealed at temperature of 4 K may be related to the small crystallite size of the Fe2TiO5 powder, which enhances the contribution of uncompensated magnetic moments at grain boundaries.
We investigate the structural and magnetic properties of Fe₂TiO₅ nanopowders prepared by ball-milling and post annealing. From the structural analysis, we observe the crystalline signature of the pseudobrookite phase. Moreover, by exploring distinct aspects of the magnetic behavior, we find fingerprints of the longitudinal spin freezing, with cluster spin glass transition taking place at 56 K, and of the presence of the Dzyaloshinskii-Moriya interaction in the system. Further, we observe antiferromagnetic features for the nanopowder at 300 K, and hysteresis loop with an abrupt change in magnetization characterizing the ferromagnetic behavior at 4 K. The results place the employed route as a simple, low-cost candidate to the production of nanopowders, especially Pseudobrookite.
Hysteresis loop of a cubic nanowire in the presence of the crystal field and the transverse field

From the magnetic hysteresis loops, we can conclude that the coercivity and remanence both decrease with increasing of temperature, so does the width of the curve. The usual hysteresis curve of a single loop gets thinner as temperature grows in a spin glass [18–20]. In order to testify the change of coercivity, we draw the coercivity versus temperature with same system parameters in Fig. 15(a).
The effective-field theory with correlations (EFT) has been used to study the various shapes of the hysteresis loop for a ferromagnetic core of spin-1 and a ferromagnetic shell of spin-3/2 with ferrimagnetic interface coupling on a cubic nanowire. The magnetizations and phase diagrams of the nanowire have been investigated in the previous work (J. Magn. Magn. Mater. 324 (2012) 4034–4042). A number of characteristic behaviors are obtained especially for the triple and multiple hysteresis loop patterns for certain values of the system parameters at low temperature. We also examine the effect of the system parameters on coercivity of the nanowire.
Magnetic and superconducting behaviours of doped and undoped double perovskite Ba<inf>2</inf>PrRuO<inf>6</inf>
2004, Physics Letters, Section A: General, Atomic and Solid State Physics
Our detailed measurements show the undoped double perovskite Ba²⁺₂Pr³⁺Ru⁵⁺O²⁻₆ to be a nonmetallic (insulating) spin glass (SG) and the ∼5–10% Cu-doped (i.e., Cu-concentration/(Cu+Ru-concentration) ∼5–10%) system to be a spin glass superconductor (SGSC), though the critical temperature, T_c, (∼8–11 K) and the superconducting volume fraction, f_sc, (∼1–4%) are small. This smallness is presumably due to the presence of a large number of pair breaking spins and small carrier concentration in the lattice. Results and their implications are discussed.
