Machine Learning Approach to Characterize Ferromagnetic La_0.7Sr_0.3MnO₃ Thin Films via Featurization of Surface Morphology. [PDF]

Adv Sci (Weinh)
A machine‐learning approach is presented to characterize ferromagnetic LSMO thin films by featurizing their surface morphology. Through an ensemble model, the non‐linear correlations between surface morphology and the electric/magnetic properties of LSMO thin films are successfully captured.

Influence of Thickness on the Magnetic and Magnetotransport Properties of Epitaxial La_0.7Sr_0.3MnO₃ Films Deposited on STO (0 0 1)

Nanomaterials, 2021
Epitaxial La0.7Sr0.3MnO3 films with different thicknesses (9–90 nm) were deposited on SrTiO3 (0 0 1) substrates by pulsed laser deposition. The films have been investigated with respect to morpho-structural, magnetic, and magneto-transport properties ...

Colossal electroresistance without colossal magnetoresistance in La0.9Sr0.1MnO3 [PDF]

Applied Physics Letters, 2007
The authors report on colossal electroresistance (ER) in the ferromagnetic insulator manganite La0.9Sr0.1MnO3. The single crystal samples exhibit a transition into a low resistive state above a certain threshold current. Pulsed measurements demonstrate that this transition is not a consequence of heating.

Theory of colossal magnetoresistance [PDF]

Current Opinion in Solid State and Materials Science, 1997
The history and recent developments in studying (colossal) magnetoresistance in perovskite manganese oxides is reviewed. We emphasize the growing evidence for strongly coupled spin, charge and lattice degrees of freedom. Together with disorder, these provide the microscopic driving forces for local and inhomogeneous textures.

Colossal electroresistance and colossal magnetoresistance in spinel multiferroic CdCr2S4 [PDF]

Applied Physics Letters, 2010
Colossal magnetoresistance (CMR) and colossal electroresistance (CER) induced by the electric field in spinel multiferroic CdCr2S4 are reported. It is found that a metal-insulator transition in CdCr2S4 is triggered by the electrical field. In magnetic fields, the resistivity ρ of CdCr2S4 responds similarly to that of CMR manganites.

Nonresonant microwave absorption in epitaxial La-Sr-Mn-O films and its relation to colossal magnetoresistance [PDF]

, 2007
We study magnetic-field-dependent nonresonant microwave absorption and dispersion in thin La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ films and show that it originates from the colossal magnetoresistance.

Sr$_{0.9}$K$_{0.1}$Zn$_{1.8}$Mn$_{0.2}$As$_{2}$: a ferromagnetic semiconductor with colossal magnetoresistance [PDF]

, 2003
A bulk diluted magnetic semiconductor (Sr,K)(Zn,Mn)$_{2}$As$_{2}$ was synthesized with decoupled charge and spin doping. It has a hexagonal CaAl$_{2}$Si$_{2}$-type structure with the (Zn,Mn)$_{2}$As$_{2}$ layer forming a honeycomb-like network ...

COLOSSAL MAGNETORESISTANCE BOLOMETER

Acta Physica Sinica, 2000
Based on the sharp resistance change near the metal-insulator transition (M-I) of the colossal magnetoresistance (CMR) materials, we design and test a new type CMR bolometer. La0.67Ca0.33MnO3 epitaxial thin films were used as the photosensitive element of the bolometer, and the optical response of this device to the He-Ne laser and the blackbody were ...
