Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors

Advanced Materials, EarlyView.
Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

Magnetization Processes in Single Domain Elliptical Permalloy Thin Films

, 2014
[[abstract]]We use the micromagnetic simulation to investigate the reversible and irreversible magnetization processes of the single-domain elliptical permalloy thin films. The reversible magnetization curve without hysteresis obtained by magnetizing the

Enhanced Magnetism in Cation‐Modulated Manganite Heterostructures

Advanced Materials Interfaces, EarlyView.
Magnetic contrast is introduced within a single manganite system via a small modulation of the cation ratio. Enhanced magnetization occurs in superlattices with small stoichiometric differences. The combined SQUID, polarized neutron reflectometry, and x‐ray absorption spectroscopy results are consistent with the interfacial electronic reconstruction ...

Ultrafast dynamics of four-state magnetization reversal in (Ga,Mn)As

, 2009
The ultrafast dynamics of in-plane four-state magnetization reversal from compressively strained (Ga,Mn)As film was investigated by magneto-optical Kerr rotation measurement. The magnetization reversal signal was dramatically suppressed upon pumping, and

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Magnetization Processes of Polycrystalline La0.7Pb0.3Mn1-xFexO3

, 2013
[[abstract]]A systematic investigation of the magnetic properties in the perovskite materials La0.7Pb0.3Mn1−xFexO3 is presented in this study. The distortion induced by Mn-site substitution is not obvious as radii of Fe and Mn are similar for low Fe ...

Helicity‐Dependent All‐Optical Switching in Bi,Ga‐Substituted Rare‐Earth Iron Garnet Films Driven by Orbital Magnetic Moment

Advanced Optical Materials, EarlyView.
Helicity‐dependent all‐optical magnetization switching was demonstrated for the Bi‐ and Ga‐substituted rare‐earth (R) iron garnet crystal thin films (Bi,Ga:RIG; R = Eu3+, Nd3+, and Y3+). The efficiency followed the order EIG > NIG > YIG. These results show the correlation between 4f orbital moment (4f〈L〉) of R3+ and helicity‐dependent optical ...

Magnetization Processes in Polycrystalline (La0.7 xNdx)Pb0.3MnO3

, 2013
[[abstract]]Magnetization processes for the Nd substitution on the La site in polycrystalline (La0.7−xNdx)Pb0.3MnO3 have been systematically studied. The low-field magnetic behavior observed in ZFC and FC curves shows a long-range spin order for La-rich ...
