The Demagnetization Plane : A new method for presenting stepwise demagnetization
application/pdfA new method using a "Demagnetization Plane" is proposed to present the results of stepwise demagnetization of remanent magnetization. This method facilitates quantitative analysis of stepwise demagnetization results, allowing distinction ...

Decoupled Spin Hall Voltage Readout for Domain‐Wall Synapses in Embedded Neuromorphic Computing
Advanced Intelligent Systems, EarlyView.Magnetic domain‐wall synapses provide nonvolatile multilevel states with linear, symmetric weight updates, making them attractive for neuromorphic hardware. However, DW MTJ readout has magnetoresistance‐limited dynamic range, while anomalous‐Hall readout suffers from weak voltage output and read/write coupling.

The Interplay of Crystal‐Field Transitions and Exchange Spin Dynamics in a Ferrimagnet
Advanced Physics Research, EarlyView.Temperature‐dependent THz spectroscopy reveals strong hybridization between Yb3+ CEF excitations and Yb–Fe exchange dynamics in Gd3/2Yb1/2BiFe5O12. Near the magnetization compensation temperature, spectral weight is redistributed between the coupled modes, while the Yb–Fe exchange mode exhibits an anomalous redshift upon cooling due to CEF‐mediated ...

The fluxgate ring-core demagnetization field
, 2006 The local demagnetization factor for the ring-core flux gate is derived analytically, based on a tangential magnetization model. The results are in good agreement with experimental data for a wide range of ring shape parameters.

Chemistry – A European Journal, EarlyView.Systematic studies of a series of new 3d–4f tetranuclear complexes revealed that the ferromagnetically coupled [Mn3Gd] complex exhibits large magnetic entropy changes, especially at higher temperatures and under lower magnetic fields. ABSTRACT A series of 3d‐4f heterometallic tetranuclear complexes, (TEA)[Mn3Gd(L)3(NO3)4(CH3CN)2] ([Mn3Gd]), (TEA)[Mn3La(

Terahertz-induced demagnetization in ferromagnets
, 2016 We experimentally demonstrate ultrafast terahertz induced demagnetization in conducting ferromagnets, Ni, Co, and Fe. At even higher excitation fluence, the materials lose their magnetic properties and then get damaged before magnetic switching takes ...
