Coexistence of exchange bias and memory effect in nanocrystalline CoCr2O4

Magnetic Memory and the Promising Magnetocaloric Effect of Sn0.6Cr0.1Ge0.3Te Solid Solution Synthesized by Sealed Tube Solid-State Reaction

“…These results suggest that temperature or intermediate changes in the applied magnetic field cannot alter the sample’s history. These findings are consistent with recent studies on the SG structure. , …”

“…As the temperature further decreases below T B , the magnetization decreases, indicating the presence of a magnetic transition in the Sn 0.6 Cr 0.1 Ge 0.3 Te sample and the observation of a super SG state. 33,53,54 Further discussion on this topic is provided in the memory effect study.…”

Magnetic nanoparticles: From the nanostructure to the physical properties

“…The variation of the calculated parameters H E and H C with H cool and T are presented in Figure 7c,d, respectively. Both H C and H E increase with H cool and almost become saturated near 1 T. Then, we can exclude that the observed phenomenology can be attributed to a minor loop effect, in accordance with recent reports [6,20]. Figure 7d demonstrates a monotonic decrease of H C and H E with an increase in temperature.…”

“…Furthermore, EB reveals a wide range of potential applications in recording media to overcome the superparamagnetic (SPM) limit [23], field sensors [24], read heads [25], giant magnetoresistance (GMR) based devices [26] and many more as well. In this regard, tuning EB-related properties by controlling variation of size [27], the thickness of core and shell [11], interparticle interactions [28] and microscopic structure of the interface of any magnetically inhomogeneous system [20] might add significant value in several application-oriented phenomena. Attempts have been made to understand the underlying physics of the EB mechanism when the variation of shape [29], size [14], surface composition [30], core to shell diameter ratio come into play [6], in a core/shell nanostructure.…”

Facile Synthesis of Spinel CoCr2O4 and Its Nanocomposite with ZrO2: Employing in Photo‐catalytic Decolorization of Fe (II)-(luminol-Tyrosine) Complex.

“…In the last several decades, many novel materials with dimensions in the nanoscale were synthesized and characterized, which including nanoparticles, nanobelts, like-flower nanostructure, nanowires, Quasi-spherical nanoparticle, and nanotubes, were prepared [1][2][3][4][5][6]. Though the design and synthesis of nanoscale materials with controllable qualities is a continuous difficulty in the area of nanoscience and nanotechnology, however, it remains important materials, that have good electrical, optical, and physical characteristics [7]. The use of nanotechnology in wastewater treatment that is produced by scientific labs or industry can make the wastewater treatment is better [8][9][10][11][12].…”
